Problem with setting up JanusGraph with Solr on k8s
Hi All,
I am trying to connect my JanusGraph instance to Solr. Both are hosted on K8s cluster.
I am using JanusGraph docker image version:1.0.0-rc2 (Looks like it is using solrJ 8.11.2)
For Solr I am using following helm charts from: https://solr.apache.org/operator/resources.html The chart version is 0.7.0 and as per release notes it is deploying Solr 8.11.0 and I am deploying Solr as SolrCloud.
I am getting following exceptions:
ERROR org.apache.tinkerpop.gremlin.server.util.ServerGremlinExecutor.<init> - Could not invoke constructor on class org.janusgraph.graphdb.management.JanusGraphManager (defined by the 'graphManager' setting) with one argument of class Settings

Logs indicate that is was able to connect to ZooKeeper.
Based on search, the error indicates a mismatch in noggit version. Looks like Solr code uses a forked version of noggit.
As per janusGraph release notes, it is tested against Solr 8.11.1
Any suggestions around how to debug or mitigate this issue?
Thanks in advance.
