Andrew Kyle Purtell updated PHOENIX-7645:
-----------------------------------------
Description:
HighAvailabilityGroup uses a LoadingCache to create and manage CuratorFramework
instances for access to ZooKeeper.
In HighAvailabilityGroup#getCurator, the CuratorFramework instance may have
some issue trying to connect to ZooKeeper. If the connection fails the
CuratorFramework instance is not closed and leaks. There is a ZooKeeper object
associated with each CuratorFramework instance that also leaks, accumulating ZK
connections that continue to try to connect for a while, and leak the
associated ZK client send and event threads.
