I am setting up a mutlinode cluster using Nifi 1.x and HDF 2.0.1 ,but getting below error:-

I have created myid at each node . each myid file has 1 ,2 and 3 as value.

@Anwaar Siddiqui

Anwaar,

The myid file value has to match the list of zookeeper servers in the order they are listed in the state-management.xml file.

For example in the state-management file, we list the zookeeper servers

<property name="Connect String">daves-nifi-cluster-2:2181,daves-nifi-cluster-3:2181,daves-nifi-cluster-4:2181</property>

so on server daves-nifi-cluster-2 the value in the myid file on that server would be 1

so on server daves-nifi-cluster-3 the value in the myid file on that server would be 2

so on server daves-nifi-cluster-4 the value in the myid file on that server would be 3

In HDF 2.0/NiFi 1.0 you need to create a state/zookeeper directory on the same level as the conf, not inside of conf, directory, make sure you put the myid file in that state/zookeeper directory
