Joseph Gresock created NIFI-5866:
------------------------------------
Summary: Cluster gets out of sync: "X is not the most up-to-date
revision."
Key: NIFI-5866
URL: https://issues.apache.org/jira/browse/NIFI-5866
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.6.0
Environment: CentOS 6.9, NiFi 1.6.0 cluster of 4, running on AWS EC2
VMs.
Reporter: Joseph Gresock
Since upgrading to 1.6.0, I have started to see this error sometimes when I try
to modify a component (start, stop, configure, move, etc.):
Node X is unable to fulfill this request due to: [12, <some uuid>, <some uuid>]
is not the most up-to-date revision. This component appears to have been
modified.
The only way I have found to resolve this is to disconnect and then delete the
node from the cluster, then try again, repeating the process until the flow can
be modified. Afterwards, I have to stop nifi on the disconnected nodes, delete
their flow.xml.gz, and let them rejoin the cluster with a fresh copy of the
flow.
This sometimes happens multiple times per day.
