             Summary: data loss during live shard split if leader dies
                 Key: SOLR-14278
                 URL: https://issues.apache.org/jira/browse/SOLR-14278
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Yonik Seeley


While trying to develop better tests for shared storage (SOLR-13101), I ran across another failure for normal replica types as well (one of the first things I do when a test fails for shared storage is to try and validate that normal NRT replicas succeed.)  The PR I'll open has a test adapted from the one in SOLR-13813 for master.

Scenario:
  - indexing is happening during shard split
  - leader is killed shortly after (before the split has finished) and never brought back up
  - there are often some missing documents at the end

While it's possible that the simulated killing of the node in the unit test is imperfect, I haven't reproduced a failure if I comment out the split command and just kill the leader.
