-------------------------------------
Summary: Support multiple instances of Cleaner
Key: HIVE-18773
URL: https://issues.apache.org/jira/browse/HIVE-18773
Project: Hive
Issue Type: Improvement
Components: Transactions
Reporter: Eugene Koifman
We support multiple Workers by making each Worker update the status of the
entry in COMPACTION_QUEUE to make sure only 1 worker grabs it. Once we have
HIVE-18772, Cleaner should not need any state we can easily have > 1 Cleaner
instance by introducing 1 more status type "being cleaned".
