Hello,
I am new to elasticsearch and trying to start in one node. It says as below.
[2018-04-12T08:45:55,908][INFO ][o.e.c.s.ClusterApplierService] [lonrs11800] new_master {lonrs11800}{YF-Mz0X1TcWrKsmEHwMrLQ}{a-BLHg_qTOKkrI2AzPPO1A}{localhost}{127.0.0.1:9300}{rack=r1}, reason: apply cluster state (from master [master {lonrs11800}{YF-Mz0X1TcWrKsmEHwMrLQ}{a-BLHg_qTOKkrI2AzPPO1A}{localhost}{127.0.0.1:9300}{rack=r1} committed version [1] source [zen-disco-elected-as-master ([0] nodes joined)]]
which shows no master nodes joined and health status shows as read. Please find my config file as below. Please help in fixing the same
cat elasticsearch.yml
======================== Elasticsearch Configuration =========================
NOTE: Elasticsearch comes with reasonable defaults for most settings.
Before you set out to tweak and tune the configuration, make sure you
understand what are you trying to accomplish and the consequences.
The primary way of configuring a node is via this file. This template lists
the most important settings you may want to configure for a production cluster.
Please consult the documentation for further information on configuration options:
https://www.elastic.co/guide/en/elasticsearch/reference/index.html
---------------------------------- Cluster -----------------------------------
Use a descriptive name for your cluster:
cluster.name: MWBW_GMH_DEV
------------------------------------ Node ------------------------------------
Use a descriptive name for the node:
node.name: lonrs11819
node.master: true
node.data: false
Add custom attributes to the node:
node.attr.rack: r1
----------------------------------- Paths ------------------------------------
Path to directory where to store the data (separate multiple locations by comma):
path.data: /opt/app/tibco/install/elasticsearch/data
Path to log files:
path.logs: /opt/app/tibco/install/elasticsearch/logs
----------------------------------- Memory -----------------------------------
Lock the memory on startup:
bootstrap.memory_lock: true
bootstrap.system_call_filter: false
Make sure that the heap size is set to about half the memory available
on the system and that the owner of the process is allowed to use this
limit.
Elasticsearch performs poorly when the system is swapping the memory.
---------------------------------- Network -----------------------------------
Set the bind address to a specific IP (IPv4 or IPv6):
network.host: "11.195.97.65"
transport.host: localhost
network.publish_host: "11.195.97.65"
Set a custom port for HTTP:
http.port: 9200
For more information, consult the network module documentation.
--------------------------------- Discovery ----------------------------------
Pass an initial list of hosts to perform discovery when new node is started:
The default list of hosts is ["127.0.0.1", "[::1]"]
Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.unicast.hosts: "11.195.97.65"
discovery.zen.no_master_block: write
For more information, consult the zen discovery module documentation.
---------------------------------- Gateway -----------------------------------
Block initial recovery after a full cluster restart until N nodes are started:
gateway.recover_after_nodes: 10
For more information, consult the gateway module documentation.
---------------------------------- Various -----------------------------------
Require explicit names when deleting indices:
action.destructive_requires_name: true
