> 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
> Hadoop 0.20.100.0-SNAPSHOT
> Subversion git://local-lm/ on branch H20s -r af2da4db0328975f929c8ece9aa8d3079fa60c4a
> Compiled by rphulari on Fri Mar 26 18:20:35 PDT 2010
> Name Node Host hdfs://localhost
> Job Tracker Host localhost
> {noformat}
> *dfsadmin -report is restricted to admin only and it shows only datanodes and does not include NN and JT information*
