Hi all, in my solr cloud one of the nodes is not connecting anymore I get the error message
"LeaderElector node exists" every second..
The log files says:
2021-04-12 13:43:12.195 INFO (zkCallback-14-thread-29) [ ]
o.a.s.c.OverseerElectionContext I am going to be the leader

I am not sure if this is connected:
One of my zookeeper crashed before and I had to restart it, the folder with
snapshot.* and log.* where not readable anymore and I had to create a new one.
Any help would be very much appreciated.
Cheers
Dirk
