Hi,

After configuration, I tried to start Hadoop 2.0.5 alpha in( HA conf) test
environment but I'm getting below errors again and again.

2013-08-13 06:35:35,276 INFO org.apache.hadoop.hdfs.server.common.Storage:

Directory /u1_pool/namenode is in an inconsistent state: namespaceID is

I have formatted the namenode many times but still getting same error
"/u1_pool/namenode is in an inconsistent state"

I'm using NFS shared edits location.

Please guide.

Thanks.
