Hi All - sorry for the repeat, but I'm at a complete loss on this. I
have a collection with 100 shards and 3 replicas each. 6 of the shard
will not elect a leader. I've tried the FORCELEADER command, but
nothing changes.
The log shows 'Force leader attempt 1. Waiting 5 secs for an active
leader' It tries 9 times, and then stops.
The error that I get for a shard in question is:
org.apache.solr.common.SolrException: Error getting leader from zk for
shard shard21
