      Work Description: kokila-19 opened a new pull request, #3822:
URL: https://github.com/apache/hive/pull/3822

   ### What changes were proposed in this pull request?
   no_auto_compaction configuration should be allowed to overridden on a database level: adding no_auto_compaction=false should override the table level setting forcing the initiator to schedule compaction for all tables.
   
   ### Why are the changes needed?
   Currently a simple user can create a table with no_auto_compaction=true table property and create an aborted write transaction writing to this table. This way a malicious user can prevent cleaning up data for the aborted transaction, creating performance degradation.
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
