Hi Sanjeet, One thing to do is make sure you're using at least Zookeeper 3.5.5:
Migrating from 1.x.x to 1.10.0 > > - The RPM creation mechanism appears broken for both Java 8 and Java > 11 binaries if you wanted to build those yourself. 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: > 1. Remove the clientPort=2181 line (or whatever your port number > may be) > 2. 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.
