Description

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 display this information in hadoop version command

I will be uploading patch which shows like NN & JT information in version command as shown below.

[rphulari@statepick-lm]> bin/hadoop version

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