Hi Frank,
Can you please confirm that Solr nodes are aware of entire ZK ensemble?
Can you give more info how it is deployed - ZK on separate servers? What
is load on Solr when it happens? Do you see any errors in Solr logs?
Thanks,
Emir

I am somewhat new to SolrCloud and ZooKeeper.
We are deploying ZK and SolrCloud on AWS.
We are noticing an issue where the one of the three nodes in the ZooKeeper ensemble
"drops out" of the ensemble (although the Java process continues to run fine
and nothing obviously bad in the ZooKeeper log files).
And (perhaps its a coincidence) but the Solr cluster then seems to be impacted where Solr
nodes appear as "gone" even though their Java process is still running.
When we restart ZooKeeper nodes the Solr Cluster does not recover.
I have ZooKeeper logs and Solr logs - just wondering what else I should capture
before posting to this mailing list
Thanks!
