Eugene Koifman commented on HIVE-17232:
---------------------------------------
The loop in CopactorInputSplit.getSplits() is expecting delta/base or original
file but ends up seeing a bucket file in an acid delta dir
> "No match found" Compactor finds a bucket file thinking it's a directory
> --------------------------------------------------------------------------
