Subject [jira] [Updated] (SOLR-9439) Shard split clean up logic for older failed splits is faulty
Date Wed, 24 Aug 2016 21:21:21 GMT


Shalin Shekhar Mangar updated SOLR-9439:
    Attachment: SOLR-9439.patch

Trivial fix is attached. The test which tickled this bug is part of SOLR-9438 but I'll try
to write a minimal test case here as well.

> In case a split finds that previous sub-shards exist in construction or recovery state.
it tries to clean them up by invoking deleteshard API. However, the clean up logic tries to
invoke deleteshard on the same sub-shards as many times as the requested number of sub-ranges.
Such repeat calls to deleteshard fail and therefore fail the entire shard split operation.
