1##################### ElasticSearch Configuration Example #####################
2
3# This file contains an overview of various configuration settings,
4# targeted at operations staff. Application developers should
5# consult the guide at <http://elasticsearch.org/guide>.
6#
7# The installation procedure is covered at
8# <http://elasticsearch.org/guide/reference/setup/installation.html>.
9#
10# ElasticSearch comes with reasonable defaults for most settings,
11# so you can try it out without bothering with configuration.
12#
13# Most of the time, these defaults are just fine for running a production
14# cluster. If you're fine-tuning your cluster, or wondering about the
15# effect of certain configuration option, please _do ask_ on the
16# mailing list or IRC channel [http://elasticsearch.org/community].
17
18# Any element in the configuration can be replaced with environment variables
19# by placing them in ${...} notation. For example:
20#
21# node.rack: ${RACK_ENV_VAR}
22
23# See <http://elasticsearch.org/guide/reference/setup/configuration.html>
24# for information on supported formats and syntax for the configuration file.

27################################### Cluster ###################################
28
29# Cluster name identifies your cluster for auto-discovery. If you're running
30# multiple clusters on the same network, make sure you're using unique names.
31#
32cluster.name: rft
33
34
35#################################### Node #####################################
36
37# Node names are generated dynamically on startup, so you're relieved
38# from configuring them manually. You can tie this node to a specific name:
39#
40# node.name: "Franz Kafka"
41
42# Every node can be configured to allow or deny being eligible as the master,
43# and to allow or deny to store the data.
44#
45# Allow this node to be eligible as a master node (enabled by default):
46#
47# node.master: true
48#
49# Allow this node to store data (enabled by default):
50#
51# node.data: true
52
53# You can exploit these settings to design advanced cluster topologies.
54#
55# 1. You want this node to never become a master node, only to hold data.
56#    This will be the "workhorse" of your cluster.
57#
58# node.master: false
59# node.data: true
60#
61# 2. You want this node to only serve as a master: to not store any data and
62#    to have free resources. This will be the "coordinator" of your cluster.
63#
64# node.master: true
65# node.data: false
66#
67# 3. You want this node to be neither master nor data node, but
68#    to act as a "search load balancer" (fetching data from nodes,
69#    aggregating results, etc.)
70#
71# node.master: false
72# node.data: false
73
74# Use the Cluster Health API [http://localhost:9200/_cluster/health], the
75# Node Info API [http://localhost:9200/_cluster/nodes] or GUI tools
76# such as <http://github.com/lukas-vlcek/bigdesk> and
77# <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.
78
79# A node can have generic attributes associated with it, which can later be used
80# for customized shard allocation filtering, or allocation awareness. An attribute
81# is a simple key value pair, similar to node.key: value, here is an example:
82#
83# node.rack: rack314
84
85# By default, multiple nodes are allowed to start from the same installation location
86# to disable it, set the following:
87# node.max_local_storage_nodes: 1
88
89
90#################################### Index ####################################
91
92# You can set a number of options (such as shard/replica options, mapping
93# or analyzer definitions, translog settings, ...) for indices globally,
94# in this file.
95#
96# Note, that it makes more sense to configure index settings specifically for
97# a certain index, either when creating it or by using the index templates API.
98#
99# See <http://elasticsearch.org/guide/reference/index-modules/> and
100# <http://elasticsearch.org/guide/reference/api/admin-indices-create-index.html>
101# for more information.
102
103# Set the number of shards (splits) of an index (5 by default):
104#
105# index.number_of_shards: 5
106
107# Set the number of replicas (additional copies) of an index (1 by default):
108#
109# index.number_of_replicas: 1
110
111# Note, that for development on a local machine, with small indices, it usually
112# makes sense to "disable" the distributed features:
113#
114# index.number_of_shards: 1
115# index.number_of_replicas: 0
116
117# These settings directly affect the performance of index and search operations
118# in your cluster. Assuming you have enough machines to hold shards and
119# replicas, the rule of thumb is:
120#
121# 1. Having more *shards* enhances the _indexing_ performance and allows to
122#    _distribute_ a big index across machines.
123# 2. Having more *replicas* enhances the _search_ performance and improves the
124#    cluster _availability_.
125#
126# The "number_of_shards" is a one-time setting for an index.
127#
128# The "number_of_replicas" can be increased or decreased anytime,
129# by using the Index Update Settings API.
130#
131# ElasticSearch takes care about load balancing, relocating, gathering the
132# results from nodes, etc. Experiment with different settings to fine-tune
133# your setup.
134
135# Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
136# the index status.
137
138
139#################################### Paths ####################################
140
141# Path to directory containing configuration (this file and logging.yml):
142#
143# path.conf: /path/to/conf
144
145# Path to directory where to store index data allocated for this node.
146#
147# path.data: /path/to/data
148#
149# Can optionally include more than one location, causing data to be striped across
150# the locations (à la RAID 0) on a file level, favouring locations with most free
151# space on creation. For example:
152#
153# path.data: /path/to/data1,/path/to/data2
154
155# Path to temporary files:
156#
157# path.work: /path/to/work
158
159# Path to log files:
160#
161# path.logs: /path/to/logs
162
163# Path to where plugins are installed:
164#
165# path.plugins: /path/to/plugins
166
167
168#################################### Plugin ###################################
169
170# If a plugin listed here is not installed for current node, the node will not start.
171#
172# plugin.mandatory: mapper-attachments,lang-groovy
173
174
175################################### Memory ####################################
176
177# ElasticSearch performs poorly when JVM starts swapping: you should ensure that
178# it _never_ swaps.
179#
180# Set this property to true to lock the memory:
181#
182# bootstrap.mlockall: true
183
184# Make sure that the ES_MIN_MEM and ES_MAX_MEM environment variables are set
185# to the same value, and that the machine has enough memory to allocate
186# for ElasticSearch, leaving enough memory for the operating system itself.
187#
188# You should also make sure that the ElasticSearch process is allowed to lock
189# the memory, eg. by using `ulimit -l unlimited`.
190
191
192############################## Network And HTTP ###############################
193
194# ElasticSearch, by default, binds itself to the 0.0.0.0 address, and listens
195# on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
196# communication. (the range means that if the port is busy, it will automatically
197# try the next port).
198
199# Set the bind address specifically (IPv4 or IPv6):
200#
201network.bind_host: localhost
202
203# Set the address other nodes will use to communicate with this node. If not
204# set, it is automatically derived. It must point to an actual IP address.
205#
206# network.publish_host: 192.168.0.1
207
208# Set both 'bind_host' and 'publish_host':
209#
210network.host: localhost
211
212# Set a custom port for the node to node communication (9300 by default):
213#
214# transport.tcp.port: 9300
215
216# Enable compression for all communication between nodes (disabled by default):
217#
218# transport.tcp.compress: true
219
220# Set a custom port to listen for HTTP traffic:
221#
222# http.port: 9200
223
224# Set a custom allowed content length:
225#
226# http.max_content_length: 100mb
227
228# Disable HTTP completely:
229#
230# http.enabled: false
231
232
233################################### Gateway ###################################
234
235# The gateway allows for persisting the cluster state between full cluster
236# restarts. Every change to the state (such as adding an index) will be stored
237# in the gateway, and when the cluster starts up for the first time,
238# it will read its state from the gateway.
239
240# There are several types of gateway implementations. For more information,
241# see <http://elasticsearch.org/guide/reference/modules/gateway>.
242
243# The default gateway type is the "local" gateway (recommended):
244#
245# gateway.type: local
246
247# Settings below control how and when to start the initial recovery process on
248# a full cluster restart (to reuse as much local data as possible when using shared
249# gateway).
250
251# Allow recovery process after N nodes in a cluster are up:
252#
253# gateway.recover_after_nodes: 1
254
255# Set the timeout to initiate the recovery process, once the N nodes
256# from previous setting are up (accepts time value):
257#
258# gateway.recover_after_time: 5m
259
260# Set how many nodes are expected in this cluster. Once these N nodes
261# are up (and recover_after_nodes is met), begin recovery process immediately
262# (without waiting for recover_after_time to expire):
263#
264# gateway.expected_nodes: 2
265
266
267############################# Recovery Throttling #############################
268
269# These settings allow to control the process of shards allocation between
270# nodes during initial recovery, replica allocation, rebalancing,
271# or when adding and removing nodes.
272
273# Set the number of concurrent recoveries happening on a node:
274#
275# 1. During the initial recovery
276#
277# cluster.routing.allocation.node_initial_primaries_recoveries: 4
278#
279# 2. During adding/removing nodes, rebalancing, etc
280#
281# cluster.routing.allocation.node_concurrent_recoveries: 2
282
283# Set to throttle throughput when recovering (eg. 100mb, by default unlimited):
284#
285# indices.recovery.max_size_per_sec: 0
286
287# Set to limit the number of open concurrent streams when
288# recovering a shard from a peer:
289#
290# indices.recovery.concurrent_streams: 5
291
292
293################################## Discovery ##################################
294
295# Discovery infrastructure ensures nodes can be found within a cluster
296# and master node is elected. Multicast discovery is the default.
297
298# Set to ensure a node sees N other master eligible nodes to be considered
299# operational within the cluster. Set this option to a higher value (2-4)
300# for large clusters (>3 nodes):
301#
302# discovery.zen.minimum_master_nodes: 1
303
304# Set the time to wait for ping responses from other nodes when discovering.
305# Set this option to a higher value on a slow or congested network
306# to minimize discovery failures:
307#
308# discovery.zen.ping.timeout: 3s
309
310# See <http://elasticsearch.org/guide/reference/modules/discovery/zen.html>
311# for more information.
312
313# Unicast discovery allows to explicitly control which nodes will be used
314# to discover the cluster. It can be used when multicast is not present,
315# or to restrict the cluster communication-wise.
316#
317# 1. Disable multicast discovery (enabled by default):
318#
319# discovery.zen.ping.multicast.enabled: false
320#
321# 2. Configure an initial list of master nodes in the cluster
322#    to perform discovery when new nodes (master or data) are started:
323#
324# discovery.zen.ping.unicast.hosts: ["host1", "host2:port", "host3[portX-portY]"]
325
326# EC2 discovery allows to use AWS EC2 API in order to perform discovery.
327#
328# You have to install the cloud-aws plugin for enabling the EC2 discovery.
329#
330# See <http://elasticsearch.org/guide/reference/modules/discovery/ec2.html>
331# for more information.
332#
333# See <http://elasticsearch.org/tutorials/2011/08/22/elasticsearch-on-ec2.html>
