             Summary: Processors on a Primary Node do not retrieve state from ZooKeeper
                 Key: NIFI-3151
                 URL: https://issues.apache.org/jira/browse/NIFI-3151
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.1.0
            Reporter: Jeff Storck


Found when testing the ZooKeeper Migrator.  If a processor running on a primary node has done some processing, and therefore has some state stored in ZK, it will retrieve state from ZK unless the primary node changes.

In the case of the ZooKeeper Migrator writing new state to ZK, the processor on the primary node will not use this new state, and will continue to process based on its current state.

When a processor is started, even when it is running on the primary node, it should check to see if there are state differences between its current state and what's in ZK, and if there are differences, it should retrieve that state.
