Re: HBase Master: Failed to become active master

Hi,

 

Can you please describe how you arrived into this? Have you tried to remove some files from HDFS or some data from ZK?

 

From the logs, sound like the master is not able to find the namespace table, so tries to create it and failed because it exist.

 

Can you paste the result of the following command?

 

hadoop fs -ls -R /hbase/data/hbase/

 

Thanks,

Re: HBase Master: Failed to become active master

I 've got many HDFS corrupt blocks and I have re-deployed the HBase service.

I did clean the HBase env before I re-installed it.

 

Here is the outcome:

Re: HBase Master: Failed to become active master

OK. The namespace table is not there.

 

So your HBase is empty, right?

 

Can you provide hadoop fs -ls -R /hbase/data/ then?

 

Have you also cleared the ZK nodes?

 

If you want to clear HBase correctly you need to:

1) Clear /hbase/* and make sure /hbase belongs to the HBase user

2) Clear all HBase zk nodes.

 

Thanks,

Re: HBase Master: Failed to become active master

I have already cleared the /hbase/* HDFS folder.

But I cannot clear the HBase zk nodes!!

When I launch zookeeper client it hangs....

 

The output is same as before:

Re: HBase Master: Failed to become active master

Hi TS, sorry, had to transit to was not able to reply yesterday.

 

So there is 2 issues here.

 

1) You can not access ZK

2) HBase can not create the namespace table.

 

They might be related. If we can not access ZK, maybe HBase can't too.

 

So let's focus on the ZK issue first.

 

Please stop all HBase services and make sure ZK is running. When you try to run the zkClient command, what do you get? What do you have on the ZK logs? Have you tried to restart the ZK service?

Re: HBase Master: Failed to become active master

Hi JM, thank you!

I have restarted ZK, but still I am unable to get the ZK Client working!
