Can the Cluster Coordinator election be sped up, nifi-1.0.0.2.0.1.0-12

I have a 3 node cluster. When I bring all three nodes down, then start them up at the same time there is always a 300 second Cluster coordinator wait. I was wondering if this process can be sped up (via a setting or a different startup procedure). During that 5 mins the UI can be seen as an independent node but no editing can be done on existing flows created with all 3 nodes of the cluster up and connected. Thanks - J.Thomas King

Hello @J.Thomas King

You can reduce the waiting time by setting nifi.cluster.flow.election.max.wait.time or nifi.cluster.flow.election.max.candidates in nifi.properties.

Please refer Clustering Configuration "Flow Election" section for detail.

Thanks,

Koji
