I enabled the Namenode High Availability using ambari.
I want to verify the connection using dfs.nameservices (nameservice ID) before start the coding.
Is there any command line or tool to verifiy it?

You can use the normal HDFS CLI. 

hdfs dfs -ls hdfs://nameservice/user

Which should also work the same as 

hdfs dfs -ls hdfs:///user

Or giving your active namenode

hdfs dfs -ls hdfs://namenode-1:port/user

If you provide the standby namenode, it will say operation READ not supported in state standby
