Eugene Koifman created HIVE-20874:

             Summary: Add ability to to run high priority compaction
                 Key: HIVE-20874
             Project: Hive
          Issue Type: New Feature
          Components: Transactions
    Affects Versions: 1.0.0
            Reporter: Eugene Koifman

currently all compaction requests (via Alter Table command or auto initiated 
(\{{}}) land in a queue (\{{COMPACTION_QUEUE}} metastore DB 
table) and are executed in order.

If the queue is long and some table/partition needs to e compacted urgently, 
there is no way to send it to the beginning of the queue.

Need a way to address this.
