Shalin Shekhar Mangar updated SOLR-3755:
----------------------------------------
Attachment: SOLR-3755.patch
Changes:
# Fixed off-by-one mistake in replica creation
# Commit before split
# Better sub-shard node addition logic using shard ranges. Defensive checks in
DUPF are modified to allow sub-shard replication. A new param
distrib.from.shard is added to forwarded requests if node list contains
sub-shard leaders.
# Modified ShardSplitTest to index docs constantly (to check sub-shard
replication).
The test fails currently because the sub-shards now have more docs than they
should have. I'm investigating this.
Patch is created on top of trunk r1459441 via git.

> we should also add a way to add additional shards dynamically by splitting
> existing shards.
