-------------------------------------
Summary: HS2 fails to clean up Spark client state on timeout
Key: HIVE-10143
URL: https://issues.apache.org/jira/browse/HIVE-10143
Project: Hive
Issue Type: Bug
Reporter: Marcelo Vanzin
Assignee: Marcelo Vanzin
When a new client is registered with the Spark client and fails to connect back
in time, the code will time out the future and HS2 will give up on that client.
But the RSC backend does not clean up all the state, and the client is still
allowed to connect back. That can lead to the client staying alive indefinitely
and holding on to cluster resources, since HS2 doesn't know it's alive but the
connection still exists.
