Hello @JPercivall @olegz @markap14 I've updated Cluster and External state
behavior in a NiFi cluster, so that only a Primary node access Zookeeper or
External data store.
Tested, with the latest master branch. Would you be able to resume review
process for this?
Now this PR contains three related JIRA issues:
- [NIFI-2078](https://issues.apache.org/jira/browse/NIFI-2078): State
managed externally
- [NIFI-2363](https://issues.apache.org/jira/browse/NIFI-2363): CLUSTER
scope should be managed on primary node
- [NIFI-2364](https://issues.apache.org/jira/browse/NIFI-2364): Avoid being
disconnected by error related to external system
Code change summaries for each topic is written in the commit message.
For External state, it's also possible to make the state external local
(per node). Please see following screenshots, fig-1 and 2.
fig-1: External - CLUSTER
fig-2: External - LOCAL, GetKafka in this image is just an example. The
actual code uses External - CLUSTER scope. There's no implementation using
External - LOCAL as of now
Thanks!
