Now, I am able to run ElasticSearch cluster of multiple 'WORKER' nodes and
with only one single 'MASTER' node.
This was resolved by configuring it in "configuration/elasticsearch.xml" as
follows :
<property>
<name>discovery.zen.ping.unicast.hosts</name>
<value>
["${@//site/global/elasticsearchmaster_host}:${@//site/global/master_tcp_port}"]
</value>
<description></description>
</property>
Putting above config in app_config itself does not work because
"${@//site/global/master_tcp_port}"
been converted to "${ELASTICSEARCHMASTER.ALLOCATED_PORT}" first and try to
allocate dynamic ports which results in different ports for
"site.global.master_tcp_port"
and "discovery.zen.ping.unicast.hosts". Hence I moved it to
"configuration/elasticsearch.xml"
which works fine for me with single MASTER instance.
It does not work with 2 or more MASTER nodes,
Now I want to know how I need to configure in order to have multiple MASTER
nodes with its ports, when I tried running for 2 instances, it resulted as
"host1, host2:port2" but what I expect is "host1:port1, host2:port2".
Please help me in resolving this. Thanks in advance.
Thanks,
Chackra
