Mark Miller commented on SOLR-5644:
-----------------------------------
I don't think that clusterstate object will ever be updated?
What about changing the splitshard method to take zkstatereader and use
zkstatereader#getleaderretry?
> SplitShard does not handle not finding a shard leader well.

> In OverseerCollectionProcessor:

> Replica parentShardLeader = clusterState.getLeader(collectionName, slice);
> This returns null if there is no current leader and the following code does
> not deal with that case and instead NPE's.
