Shalin Shekhar Mangar updated SOLR-3755:
----------------------------------------
Attachment: SOLR-3755.patch
Patch updated to trunk.
Changes:
# Router and range for the current core is used during split
# Change sub-shard replication to check only sub shard range instead of state
# Fixed replica allocation code such that replicas are not created on the same
node always
# Splitting a sub-shard works
# Slice state and range kept in CloudDescriptor is used one-time only. DUPF and
other places rely on state/range read from ZK.
# Removed multiple debug statements, sleeps and nocommits
> shard splitting

> We can currently easily add replicas to handle increases in query volume, but
> we should also add a way to add additional shards dynamically by splitting
> existing shards.
