Subject Re: 3 node of nifi generating 3 different flow files
Date Fri, 19 Jun 2020 00:15:59 GMT
Hi Andy,
Already tried by deleting flow.xml.gz ,users.xml,authorization.xml file of
3 nodes.
But still getting the same error.

in nifi-app.log is showing exception that" local flow is differet than
cluster flow"

Also new flow.xml.gz file is having different 'rootGroupid' on each node
Thanks.
Sanjeet
