Check the value configured in 'zookeeper.znode.parent'. There could
be a mismatch with the one configured in the master
Hi,
We are using hbase-0.94.1
While trying to access hbase with API all of suddenly we got following exception in our production cluster:
"from org.apache.hadoop.hbase.zookeeper.ZooKeeperNodeTracker in pool-61-thread-3Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master"
Due to this issue our application not responding for at least 15 to 20 minutes and after this time its started responding automatically.
We are unable to get any clue about it, can someone help us to resolve this issue.
Thanks,Sandeep.

Hi ,
I am very new using hbase.
I am also facing the same issue :
I started the hbase shell and then executed the list command.
Got the following error.

Zookeeper Quorum is running fine at without any issue. I also checked zookeeper logs in all quorum machines and I don't seen any errors in logs.
Thanks,Sandeep.

Is your zookeeper running fine? I suspect the random zk node that the
client is trying to connect to is coming out of the quorum and then
rejoining back due to some problem. You can check the zk logs for that.

I rechecked and all client side zk configs are in sync and it was working before and suddenly stopped working with the exception. After some time again it started working.We are facing same issue repeatedly.

Are the client side zk configs in sync with the other nodes? Was it working
before and suddenly stopped working now?
