Unicast discovery fails to connect to master

In addition to my previous question, is it correct that version 0.90.11
only pings one port, instead of the entire 9300-9400 range?

Is the master node under pressure? I meant pressure on memory (JVM old generation GC).

Ping will ping one port.
If you did not set port in unicast list, 9300 is assumed I guess.

Modify elasticsearch.yml file and set the "right" port for this node.

Hi David,

Ok, I think the latter (the port range) is the actual issue. Would you be
able to think with me on a possible solution?

We run 3 ES applications per node, each with 2-4 ES clients. Would it then
be best to specify
b001.my-cluster.com[9300-9312],b002.my-cluster.com[9300-9312]
et cetera?

Not sure about your architecture. May be you have good reasons for that but running more than one node per machine is not what I'd recommend.
But here, may be they are "client only nodes"?

Specifying port range is OK. When your node starts, it tries to ping b001:9300, then b001:9301, …
One node should at least answer otherwise, current node will think it's alone and will set itself as master.

Once the cluster state is get from master node to the current node, current node knows exactly which nodes forms the cluster and on which port for each node.
So, when pinging, only the right port is pinged. If the expected node does not answer to ping request, it will be considered as leaving the cluster.

Makes sense?

Hi David,

Ok, I think the latter (the port range) is the actual issue. Would you be able to think with me on a possible solution?

We run 3 ES applications per node, each with 2-4 ES clients. Would it then be best to specify b001.my-cluster.com[9300-9312],b002.my-cluster.com[9300-9312] et cetera?

If you did not set port in unicast list, 9300 is assumed I guess.

Modify elasticsearch.yml file and set the "right" port for this node.

Hi David,

Yes, that makes sense. Thank you for helping me out.

Some background on the architecture, there is one ES server, and 2 other
applications that are client only. However the order of starting these
services is random (e.g. it is unsure which service picks the 9300 port).
