Re: Issues while configuring nifi cluster
Images do not come through consistently on this email list, so please host that elsewhere and link to it, or copy/paste the content of it.
Without seeing the image, I am not positive, but based on the other text in your email, I suspect your nifi.sensitive.props.key value is empty in nifi.properties. This is not a blocker but is strongly discouraged.
The second issue is likely a malformed XML file in users.xml or authorizers.xml. It could also be the flow.xml.gz file. Without additional debugging information (further stack trace, those XML files), we will not be able to help more than that. If you can share those, please do.

Hello Andy,
Thanks for your support, I have deleted the flow.xmlgz file and restarted
both the nodes. Now the Cluster has been connected after restarting the
nodes.
Thanks,

Re: Issues while configuring nifi cluster
Posted by Andy LoPresto <al...@apache.org>.
The message about the blank sensitive properties key is important and is informing you that the sensitive configuration values are not being protected because that key has not been set. However, it is not blocking any operations from occurring.
The subsequent messages are telling you that the Flow Registry does not contain the specific version (version 2) of one of the flows being used, so the node cannot sync with it. Then it reports that the node cannot join the cluster because the local flow is not the same as the cluster flow. If you have made local changes and want to keep them, you’ll have to perform manual synchronization on the cluster nodes to duplicate those changes. If not, you can delete the flow.xml.gz file from the local node’s conf/ directory and after restarting, the node will inherit the cluster flow.
For node 2, the same message as the beginning of node 1 is occurring. You should check that your Flow Registry is configured correctly and has the most recent version of the flow under version control.
