-------------------------------
Summary: Create a new configuration to override "no compaction"
for tables
Key: HIVE-26793
URL: https://issues.apache.org/jira/browse/HIVE-26793
Project: Hive
Issue Type: Improvement
Reporter: Kokila N
Assignee: Kokila N
Currently a simple user can create a table with
{color:#6a8759}no_auto_compaction=true{color} 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.
This configuration should be allowed to overridden on a database level: adding
{color:#6a8759}no_auto_compaction=false{color} should override the table level
setting forcing the initiator to schedule compaction for all tables.
