Sanjeet, I’d recommend grabbing a thread dump while NiFi is starting up (after it’s been going for 3 minutes or so) and providing that to understand why it’s taking 30 minutes to startup. Specifically, the “main” thread will be of interest.

Should be resolved in a later release. * We've removed the following nars from the default convenience binary. These include kite-nar, kafka-0-8-nar, flume-nar, media-nar, druid-controller-service-api-nar, druid-nar, other-graph-services-nar. You can still get them from the various artifact repositories and use them in your flows but we cannot bundle them due to space limitations by default. * The "Auto-Create Partitions" property was removed from the PutHive3Streaming processor, causing existing instances of this processor to become invalid. The property would appear as a unsupported user-defined property and must be removed to return the processor to a valid state. * The Zookeeper dependency that NiFi uses for state management and cluster elections was upgraded to v3.5.5. From v3.5.x onwards, Zookeeper changed the zookeeper.properties file format and as a result NiFi users using an existing embedded zookeeper will need to adjust their existing zookeeper.properties file accordingly. More details here: https://zookeeper.apache.org/doc/r3.5.3-beta/zookeeperReconfig.html#sc_reconfig_clientport. For new deployments of the 1.10.0 release onwards, NiFi will be packaged with an updated template zookeeper.properties file. To update an existing zookeeper.properties file however, edit the conf/zookeeper.properties file: * Remove the clientPort=2181 line (or whatever your port number may be) * Add the client port to the end of the server string eg: server.1=localhost:2888:3888;2181 You may also need to ensure your server certificates contain a DNS entry in the Subject Alternative Name (SAN) for their respective hosts.

When i am starting the 1.11.4 cluster with this new files, i am getting node disconnected error (this node is not conncted to cluster pop up ) However with only users.xml, authrization.xml from 1.8 and default 1.11.4 flow.xml.gz. i am getting no error all 3 nodes are getting conncted in the new cluster. Infact when i am bringing another 1.8 env's flow.xml.gz files it working fine. So specific for this flow.xml.gz file only my nodes are getting disconncted. It will really helpfull if you can help where i need to check to resolve this issue. I am using external zookeeper 3.5 version Thanks in advance, Sanjeet -- Sanjeet Kumar Rath, mob- +91 8777577470
