> SEGMENT_INDEX compaction is not taking compaction lock. While concurrent operation, this may be successful but the output may not be as expected.
> Scenario:
> Execute MINOR compaction and SEGMENT_INDEX compaction concurrently.
> As SEGMENT_INDEX compaction is not taking any lock it will do tasks in between, finally some segments index files will be merged, probably the newly created segments may be left out.
> Solution:
> To take compaction lock
