ambari hdfs rebalance failed (RpcNoSuchMethodException)

Hi, All

I met a problem when rebalancing hdfs as follows: 
ambari : 2.1.2.1

Is there anyone have an idea about this? 

and where is the script of 'start-balancer.sh' ? 

.....

Looks like you are hitting a bug.

https://issues.apache.org/jira/browse/AMBARI-13373

WORKAROUND:

Use the configs.sh utility on the Ambari Server to delete the extra property.

Important: Only perform this procedure if your cluster is running NameNode HA and you are experiencing the HDFS balancer issue.

/var/lib/ambari-server/resources/scripts/configs.sh -u <admin.user> -p <admin.password> delete

<ambari.server> <cluster.name> hdfs-site “dfs.namenode.rpc-address”

Where

admin.user and

admin.password are credentials for an Ambari Administrator,

ambari.server is the Ambari Server host and

cluster.name is the name of your cluster.

thanks for your reply in advance.

Is there any impact on hadoop operations after "config.sh delete ... hdfs-site “dfs.namenode.rpc-address" command runs?

@Young-Geun Park

No, we need to restart couple of services I guess.
