When there are multiple HMSes we need to > have a leader HMS elected which will carry out those housekeeping tasks. > These tasks include execution of compaction tasks, auto-discovering > partitions for external tables, generation of compaction tasks, repl thread > etc. > Note that, though the code for compaction tasks, auto-discovery of partitions > etc. is in Hive, the actual tasks are initiated by an HMS configured to do > so. So, leader election is required only for HMS and not for HS2. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
