-------------------------------------

             Summary: Enhancing Hive Metastore common library support for Leader Election
                 Key: HIVE-27259
                 URL: https://issues.apache.org/jira/browse/HIVE-27259
             Project: Hive
          Issue Type: Improvement
          Components: Standalone Metastore
            Reporter: Subhasis Gorai


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.
