HA cannot formt standby namenode

Hi,

I change my cluster to HA and it failed on bootstrapping the standby namenode.

Failed to bootstrap Standby NameNode namenode (nrmcdhnn02): STARTUP_MSG:   build = http://github.com/cloudera/hadoop -r b739cd891f6269da5dd22766d7e75bd2c9db73b6; compiled by 'jenkins' on 2015-07-07T00:02Z

When I try to start nn2, it states that it's not formatted.

Any suggestions? (CDH 5.4.4)

Thanks,

I copied dfs directory from the active namenode to the standby namenode and restarted it.

It solved the problem. Thanks.
