Summary: Processors on a Primary Node do not retrieve state from ZooKeeper

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.
