I have a 3 node nifi cluster with host name as nifi-hatest-01, nifi-hatest-02, nifi-hatest-03.
nifi-hatest-01 is primary node at the moment and I can see (in logs) it is receiving heartbeats from 02 & 03.
And if I create flows in any one of the 3 nodes it gets sycned to all nodes.
But the problem now is the 3rd node (nifi-hatest-03) does not show up in the "cluster" tab of Nifi UI.
Any idea what could be the issue?
any suggestion would be much appreciated.

Although 2 nodes showing connected , we should also see the time stamps under column started At and LastHearbeat . also I am expecting to see coordinator and primary under status column.
it is not clear from attached snap, as in from which node you are trying to access the UI ? if you open UI from each node 1,2, and 3 what you see? Is 3rd is showing as disconnected ?
have you checked the process id's of nifi on 3rd node?
How zookeeper is used ? External user or embedded zookeeper ?
Hi @ckumar - thanks for the reply.
I think that screenshot lacked info may be due to my permission issue.
Same issue has been posted by team mate here - https://community.cloudera.com/t5/Support-Questions/NiFi-Node-showing-2-nodes-and-not-respecting-nod...
Please take a look at the screenshot attachment there which has more info.
And i can login from all 3 nodes ui, and in all nodes it shows up only 1 & 2.
