FAILED TO WRITE PID installing Zookeeper

Question

I am new to Zookeeper and it has being a real issue to install it and run. I am not sure what is wrong in here but I will explain what I\'ve being doing to make it more clear:

Answer 1

I have faced the same issue while starting the zookeeper with this command:

hadoop@ubuntu:~/hadoop/zookeeper/zookeeper-3.4.8$ bin/zkServer.sh start

ERROR [main] client.ConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper.

It should have been written by the master. Check the value configured in zookeeper.znode.parent. There could be a mismatch with the one configured in the master.

But running the script as su rectified the issue:

hadoop@ubuntu:~/hadoop/zookeeper/zookeeper-3.4.8$ sudo bin/zkServer.sh start

ZooKeeper JMX enabled by default Using config: /home/hadoop/hadoop/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg Starting zookeeper ... STARTED
