Summary: Improve Nifi Cluster Behavior In Down Scenarios
Key: NIFI-3693
URL: https://issues.apache.org/jira/browse/NIFI-3693
Project: Apache NiFi
Issue Type: Improvement
Components: Configuration Management
Reporter: Tommy Young
Improve Nifi cluster behavior by allowing nodes to receive flow changes when
not all cluster nodes are online, so long as the node(s?) receiving the changes
are registered/active with Zookeeper. Then when require down nodes to update to
latest flow version with cluster before cluster re-join is completed. This
would probably require external/non-embedded zookeeper to insure valid quorum.
For any flow files already queued up on a node, process them on the old flow
prior to changing to the new flow and make sure flow is current before starting
any processors consuming data from outside systems.
This was born out of a situation where one of our pre-prod cluster nodes has
been down for nearly a week, and the cluster being read-only until all nodes
are back online has prevented any further development work from being done.
