Mark Payne 749d05840b NIFI-8204, NIFI-7866: Send revision update count in heartbeats. If update count in heartbeat is greater than that of cluster coordinator, request that node reconnect to get most up-to-date revisions. Cannot check exact equality, as the values may change between the time a heartbeat is created and the time the cluster coordinator receives it. However, it should be safe to assume that the revision won't be greater than that of the cluster coordinator. There is a tiny window in which it could be, as the sending node may update its revision, create the heartbeat, send it, and cluster coordinator process it before updating its own revision. However, this window is incredibly small and would only result in the sending node reconnecting, which will resolve itself. Also, when testing this fix, encountered NIFI-7866 and addressed that NullPointerException. ... This closes #4806. Signed-off-by: Bryan Bende <bbende@apache.org>		2021-02-05 15:18:44 -05:00
