-----------------------------------------
Summary: collections?action=SPLITSHARD parent vs. sub-shards
numDocs
Key: SOLR-5213
URL: https://issues.apache.org/jira/browse/SOLR-5213
Project: Solr
Issue Type: Improvement
Components: update
Affects Versions: 4.4
Reporter: Christine Poerschke
The problem we saw was that splitting a shard took a long time and at the end
of it the sub-shards contained fewer documents than the original shard.
The root cause was eventually tracked down to the disappearing documents not
falling into the hash ranges of the sub-shards.
Could SolrIndexSplitter split report per-segment numDocs for parent and
sub-shards, with at least a warning logged for any discrepancies (documents
falling into none of the sub-shards or documents falling into several
sub-shards)?
Additionally, could a case be made for erroring out when discrepancies are
detected i.e. not proceeding with the shard split? Either to always error or to
have an verifyNumDocs=false/true optional parameter for the SPLITSHARD action.
