I am getting this error while starting standalone hBase on my ubuntu machine. Please help. Spent a huge amount of time to get it running. :(

What I have checked so far -

  1. /etc/hosts contains localhost 127.0.0.1
  2. HBase : hbase-0.98.3-hadoop2-bin.tar.gz
  3. Hadoop: hadoop-2.6.0.tar.gz
  4. I already have the node /hbase-unsecure in my hbase-site.xml.

When I try to run the command - create 'usertable', 'resultfamily'

It gives me following exception -

ERROR: The node /hbase-unsecure 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.

did you clean up zookeeper data directory from previous trials ? by default zookeeper.znode.parent is /hbase ,

options you can try

  1. if you are changing it intentionally then changing zookeeper data directory when changing it. In /home/hduser/zookeeper
  2. try changing znode.parent to /hbase

    I was just a newbie and got it all mixed up from various Stack Overflow posts. So the problem with me was, I was not having /hbase-unsecure location in my root directory. – Sankalp Mar 22 '15 at 00:42
  • Hi, I am facing the same issue. I need to know where was the /hbase-unsecure created? what do you mean root directory? whose root directory? HBase's or Zookeeper's. I have one in both and I am facing this issue. – Anonymous Person Sep 12 '16 at 12:08
  • Hi Sankalp am facing the same problem. which root location are you talking abt? can you give us steps to do it – Chaman Nov 07 '19 at 06:15
