Re: Flow.xml.gz are Empty
I went through the nifi.properties for my ncm and two nodes and made sure that the "nifi.sensitive.props.key" values are all the same. However, I do not know how to make sure my ports are clear between the nodes. Could you help me or direct me to to some resources? >Make that your 'nifi.sensitive.props.key" is the same between all the >nodes.

Re: Flow.xml.gz are Empty
You can check a couple of things. Make that your 'nifi.sensitive.props.key" is the same between all the nodes. If it is not, you will get a partial load of the file, basically up until the point something gets loaded that needs to be decrypted. Make sure that your ports a clear between all the nodes. There are 3 ports that you need to open for clustering. Sounds simple, but lots of time, people get 2 out of 3 on one of the boxes.

Flow.xml.gz are Empty
Good morning guys, I've been having trouble connecting two slave nodes to the ncm. In the logs, on the line before "/unable to load flow due to... ConnectionException... local or cluster flow is malformed/," I see /[Fatal Error] :3384:23: Character reference "&#/ Prior to this, I deleted flow.xml.gz from the nodes because the nodes build their flow.xml.gz from the NCM's flow.tar, yet I still have the malformed flow issue. Any ideas? I can always give more information. -- View this message in context: http://apache-nifi-developer-list.39713.n7.nabble.com/Flow-xml-gz-are-Empty-tp8503.html Sent from the Apache NiFi Developer List mailing list archive at Nabble.com.
