Till Rohrmann created FLINK-6078: ------------------------------------ Summary: ZooKeeper based high availability services should not close the underlying CuratorFramework Key: FLINK-6078 URL: https://issues.apache.org/jira/browse/FLINK-6078 Project: Flink Issue Type: Bug Components: Distributed Coordination Affects Versions: 1.3.0 Reporter: Till Rohrmann Assignee: Till Rohrmann Fix For: 1.3.0
ZooKeeper based high availability tools like {{ZooKeeperLeaderRetrievalService}} and {{ZooKeeperLeaderElectionService}} expect that every instance of the services have a dedicated {{CuratorFramework}} instance assigned. Thus, they also close this {{CuratorFramework}} when the service is closed. This does not play well along with the newly introduced {{HighAvailabilityServices}} which caches a single {{CuratorFramework}} and shares it among all created services. In order to make it work properly together I propose to change the behaviour such that we no longer close the {{CuratorFramework}} clients in the ZooKeeper based services. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
