> HMS performs housekeeping tasks. 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.
