--------------------------------
Summary: Nodes in cluster should use ZooKeeper to store heartbeat
messages instead of sending to NCM
Key: NIFI-1678
URL: https://issues.apache.org/jira/browse/NIFI-1678
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
Fix For: 1.0.0
Currently, nodes send heartbeats to the NCM periodically in order to indicate
that they are actively participating in the cluster. As we move away from using
an NCM, we need these heartbeats to go somewhere else. ZooKeeper is a
reasonable location to push the heartbeats to, as it provides the HA that we
need
