> 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.

> [rphul...@statepick-lm]> bin/hadoop version
