ASF GitHub Bot logged work on HIVE-26793: ----------------------------------------- Author: ASF GitHub Bot Created on: 01/Dec/22 05:55 Start Date: 01/Dec/22 05:55 Worklog Time Spent: 10m 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?
