veghlaci05 opened a new pull request #3000:
URL: https://github.com/apache/hive/pull/3000


   ### What changes were proposed in this pull request?
   Minor compaction is not possible on table with no-acid data (either in delta 
or original files).
   This PR prevents executing a minor compaction on tables matching the 
criteria above. Furthermore,
   for these tables, the initiator will submit a MAJOR compaction instead of 
MINOR.
   
   ### Why are the changes needed?
   Executing MINOR compactions on tables with non-acid data will result in an 
NPE, when trying to apply the acid schema on a non-acid row.
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   Through automated tests.
