I am just a beginner in learning elastic search and started to setup 2 node cluster on windows 10 box.
I have configured the two nodes based on the forums and articles.
However, I am able to start the first node but when starting the second node, it throws an error.
[2018-11-05T16:07:31,935][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [elastic_search_node_02] uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: failed to obtain node locks, tried [[C:\Elastic_search_cluster\data\elastic_search_cluster]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?
The following is the setup for both the nodes,
Node 1 dir
C:\Elastic_search_cluster\elasticsearch-6.4.2_node01\
Node 2 dir
C:\Elastic_search_cluster\elasticsearch-6.4.2_node02\
Data folder
C:\Elastic_search_cluster\data\
Logs folder
C:\Elastic_search_cluster\logs\
Node 1 configuration
cluster.name: elastic_search_cluster
node.name: elastic_search_node_01
node.master: true
node.data: true
path.data: C:\Elastic_search_cluster\data\
path.logs: C:\Elastic_search_cluster\logs\
network.host: localhost
http.port: 9200
Node 2 configuration
cluster.name: elastic_search_cluster
node.name: elastic_search_node_02
node.master: false
node.data: true
path.data: C:\Elastic_search_cluster\data\
path.logs: C:\Elastic_search_cluster\logs\
network.host: localhost
http.port: 9201
Please advise on the configuration or any other recommendation. Does the data and logs folder path need to be separate for each node.
Do i need to set other parameters like the below ?
discovery.zen.ping.unicast.hosts:
discovery.zen.minimum_master_nodes:
Make sure node.max_local_storage_nodes param is set to # of nodes in cluster locally ( In your case 2 ) . I notice that you already have node names different.
in yaml ,
node.max_local_storage_nodes: 2
