Christine Poerschke created SOLR-5326:
-----------------------------------------
Summary: admin/collections?action=SPLITSHARD support for multiple
shards
Key: SOLR-5326
URL: https://issues.apache.org/jira/browse/SOLR-5326
Project: Solr
Issue Type: New Feature
Affects Versions: 4.4
Reporter: Christine Poerschke
The problem we saw was that splitting one shard took 'a long time' (around 4
hours) and with there being 'many' (8 at the time) shards to split and the solr
overseer serialising action=SPLITSHARD requests a full collection split would
have taken 'a very long time'.
Separately, shard splitting distributing replica2, replica3, etc. of each shard
randomly across machines was not desirable and as in SOLR-5004 splitting into
'n' rather than '2' sub-shards was useful.
