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 --

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

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