> hive hcatalog streaming will also create a file like bucket_n_flush_length in 
> each delta directory. Where "n" is the bucket number. But the 
> compactor.CompactorMR think this file also needs to compact. However this 
> file of course cannot be compacted, so compactor.CompactorMR will not 
> continue to do the compaction. 
> Did a test, after removed the bucket_n_flush_length file, then the "alter 
> table partition compact" finished successfully. If don't delete that file, 
> nothing will be compacted. 
> This is probably a very severity bug. Both 0.13 and 0.14 have this issue
