zookeeper starting problem

Question

I have installed zookeeper and done all the configurations needed, but when I started zookeeper with the command:

sudo /home/hduser/zookeeper/bin/zkServer.sh start

It was showing zookeeper started and then I used a command jps there were No QuorumPeerMain and when I used sudo jps I get this:

 -- process information unavailable
 QuorumPeerMain
 -- process information unavailable
 -- process information unavailable
 Jps
 -- process information unavailable
 -- process information unavailable

There's the QuorumPeerMain, why it is happening can anyone tell me?

Answer 1

Hey,

The QuorumPeerMain service is visible with sudo jps command because you are running the Zookeeper with

 sudo /home/hduser/zookeeper/bin/zkServer.sh. 

You should run the Zookeeper without sudo in command then it will be visible in jps command result.

As you have started the Zookeeper with sudo the Zookeeper directory is having the files with root permissions you have to update the owner of these directories to run it with normal command.

Once you make above changes the hbase installation will not create any problem. That's why when you mentioned you have to change the ownership of the zookeeperData folder using below command: 

sudo chown -R hduser:hduser /home/hduser/zookeeperData
