It seems that the zk server is not started. Kafka needs zookeeper, you need to download and start zookeeper before start kafka server.
I followed the below tutorial to setup nifi cluster. Performed everything as mentioned, but receiving the below error.
https://pierrevillard.com/2016/08/13/apache-nifi-1-0-0-cluster-setup/
But the zookeeper was unable to elect a leader and getting the following error message.

After Bryan's comment, got reminded that I forgot to disable the iptables (I guess I can even open the ports but since this is for my practice I am disabling the iptables) and its working now.
Getting below when trying to connect to zookeeper url using java
.Any pointers will be helpful

My Concern is what does this "Will not attempt to authenticate using SASL (unknown error) " means ?
Is this an issue .If so how this can be resolved?
Thanks and Regards
Jinesh Luke
I have solved this issue by clustering zookeeper
I am running a simple program
TitanGraph bg = TitanFactory.open("/home/titan-all-0.4.2/conf/titan-cassandra-es.properties");
IdGraph g = new IdGraph(bg, true, false);
Vertex v = g.addVertex("xyz132456");
g.commit();
Here there is no vertex xyz132456 exist before but i am getting following exception. I am getting this exception very frequently. My titan server(0.4.2) is configured with all default settings as i am just testing simple operations with this.
