[GitHub] [solr-operator] iampranabroy opened a new issue, #477: Support Zookeeper `probes` inputs via Apache Solr Operator helm charts

iampranabroy opened a new issue, #477:
URL: https://github.com/apache/solr-operator/issues/477

   #### 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**](https://github.com/pravega/zookeeper-operator/issues/315#issuecomment-824555225), they are suggesting increasing the `probes.readiness.initialDelaySeconds` from default `10` to `30/60` sec.
   Can we add support for the zookeeper `config.*` [**parameters**](https://github.com/pravega/zookeeper-operator/tree/v0.2.14/charts/zookeeper#configuration) in Apache Solr Operator helm charts?

   @mmoscher We can definitely add probes support through the Solr Operator, but just to make sure you solved this issue independently from any Solr/ZK settings correct?

   However, can confirm that the described solutions, i.e. increasing the livenessProbe.initialDelaySeconds, works. Setting this to 30s I was able to successfully deploy a zookeeper cluster with replicas > 1.

   Hey @mmoscher - As of now, **NO**. If you can raise a PR that would be great. 
   @HoustonPutman - If there are any upcoming minor releases, can we add this item?

   @HoustonPutman yes, solved it without using any probes.
   The problem was related to wrong NetworkPolicies and old (maybe corrupted) configs in the zookeeper PVC, cf. https://github.com/pravega/zookeeper-operator/issues/315#issuecomment-1259187314

   @iampranabroy did you found an interim solution?
   Facing the same issue and I think (for now) the only way to go is to deploy an separated zookeeper cluster.
   
   Will dig into this and will submit an PR. Shouldn't be that hard I think.

   @iampranabroy yes, all resources (Solr + ZK) in the same namespace with NetworkPolicies denying all pod's egress traffic.

   Hey, @mmoscher  - Thanks for your response.
   In my case, I have the Solr cluster and zookeeper cluster deployed in the same namespace, but I have seen this error several times. If we can add the support for `probes.readiness.initialDelaySeconds`, we can see if that resolves the problem.
