I have a running cluster with 3 nifi nodes, all running an embedded zookeeper. Now I want to add a fourth node which doesn't run an embedded zookeeper. What I did was, on the new node edited the nifi properties, changed nifi.cluster.is.node to true, and added the first 3 nodes zookeeper url to nifi.zookeeper.connect.string. Once done I started nifi, however I get the below error. Posting the full stack trace, this stacktrace keeps on coming infinitely:
Below is a longer stack-trace right from startup till the error:
Hi @Kamal Sehgal , Can you share some useful link about how did u setup the cluster because I am also configuring NiFi cluster with 3 machines (1 Manager and 2 Nodes) but could not be able to configure it yet. My NiFi version is 1.8.0 and using external Zookeeper instead of embedded Zookeeper.
Hi @Kamal Sehgal:
What is the issue that you are facing.
Also I found this useful:
Its actually easier using an external zookeeper(first link has the steps) . In case you get stuck, let me know.
Also there is no concept of manager node in nifi now. Refer to, https://hortonworks.com/blog/apache-nifi-1-0-0-zero-master-clustering/
Hi @siddharth pande, I am also configuring NiFi cluster with 3 machines (1 Manager and 2 Nodes) but could not be able to configure it yet. Can you share some useful link in this regard. My NiFi version is 1.8.0 and using external Zookeeper instead of embedded Zookeeper.
