Support Zookeeper probes parameters in Apache Solr Operator helm charts. #477
Description
Describe the issue:
When deploying SolrCloud via Apache Solr Operator with ensembled Zookeeper, sometimes one of the zookeeper pods gives the below error during the start:
2021-03-29 13:33:56,645 [myid:2] - ERROR [main:QuorumPeerMain@113] - Unexpected exception, exiting abnormally
java.lang.RuntimeException: My id 2 not in the peer list
at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:1073)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:227)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:136)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:90)
Possible solutions:
As per the discussions in the GitHub issue-315, they are suggesting increasing the probes.readiness.initialDelaySeconds from default 10 to 30/60 sec.
Can we add support for the zookeeper config.* parameters in Apache Solr Operator helm charts?
