ShardSplit errors..

[Annette Newton <an...@servicetick.com>]

Hi,

I have been trying to split a shard with little success.  I'm probably
missing something obvious but would appreciate a little help.

Solr version: 4.6.0
Number of documents in the Shard: 2,933,059
Index size: 6.52

I know I have some setting somewhere that I need to change but I believe I
have changed everything available.

At first I had a write.lock timeout so I upped that setting and got passed
it.

Command:

curl '
http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=sessionfilterset&shard=shard1
'

Message returned:

<?xml version="1.0" encoding="UTF-8"?>

During the run time I'm not convinced it's doing anything.  No split
directory is created, CPU remains very low and memory doesn't seem to spike.

Any help would be greatly appreciated.
