-----------------------------------
Summary: Split removeDuplicateCompletedTxnComponents away from
AcidHouseKeeper and onto a separate timer
Key: HIVE-27022
URL: https://issues.apache.org/jira/browse/HIVE-27022
Project: Hive
Issue Type: Improvement
Reporter: Jason Phelps
The operations and queries involved with removeDuplicateCompletedTxnComponents
are much costlier than the rest of the AcidHouseKeeper jobs. The default timer
for metastore.acid.housekeeper.interval is 60s [0], which is much too frequent
for removeDuplicateCompletedTxnComponents, but fine for the other operations.
There is no way of lowering the internal for just
removeDuplicateCompletedTxnComponents without impacting the other
AcidHouseKeeper jobs, so I am requesting that it be split into its own
process/timer
