Eugene Koifman updated HIVE-20874:
----------------------------------
Description:
currently all compaction requests (via Alter Table command or auto initiated
({{Initiator.java}}) 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 be compacted urgently,
there is no way to send it to the beginning of the queue.
Need a way to address this.
