The node /hbase-unsecure is not in ZooKeeper. Chec

问题:

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.

回答1:

Can you verify that hbasee-unsecure folder is present in your zookeeper?

You can just login into zookeeper by using below command and do ls.

zookeeper-client

Above command will open zookeeper shell and then do ls.

ls /

This will show folders present with zookeeper.

It should have hbase-unsecure folder in it.

Need to check the HBase log for the errors, most commonly the solution is setting correct parameters in the HBase-env.sh file.
