> I couldn't find Leader Election support in Hive metastore foundational
> libraries.
> In a distributed environment, we often need to select a node as the leader to
> coordinate the execution of complex jobs. Working on a Hive Replication
> enhancement where we need to spawn threads with specialized work but we need
> to make sure that such an HS2 thread is running strictly on a single HS2
> instance at a given moment.
> We need to enhance HMS common libraries to include the 'Leader Election'
> recipe.
