New hadoop command to show NameNode & JobTracker assosiated with client.
------------------------------------------------------------------------

                 Key: HADOOP-6636
                 URL: https://issues.apache.org/jira/browse/HADOOP-6636
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Ravi Phulari


Currently there is no command to show NameNode and JobTracker associated with client node.
Work around used for this is to grep for $HADOOP_CONF_DIR/hdfs-site.xml and mapred-site.xml
. 

This process is very tedious when more than 1 hadoop clusters are configured. 

We can add hadoop command option to show which Name node and Job tracker is associated with
client. 

Command should work something like -- 

{noformat}
[user@clientNode ~]$hadoop clusterInfo
NameNode -  nnNode.foo.corp.com:50070
JobTracker -  jtNode.foo.corp.com:50030
{noformat} 

*dfsadmin -report is restricted to admin only and it shows only datanodes and does not include
NN and JT information*
