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?
