Hi
Running SolrCloud with a Solr loosing its zookeeper connection while
having a replica I see the below log message repeatedly and the shard
never recovers. The Solr has successfully reconnected to ZooKeeper and
ZooKeeper is running fine.
I know that the cause is the loss of the ZooKeeper connection and I will
work on that, but I can guarantee that one of my ZooKeepers will go down
at some point (e.g. by a system admin), so I need the recovery to work.
I can see the code has changed recently just in this area.
Do anyone have a hint of what I may do to get more information about this?
Thanks in advance for any comments.
Best regards Trym
