[jira] Created: (HADOOP-6636) New hadoop command to show NameNode &
JobTracker assosiated with client.
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*

[jira] Commented: (HADOOP-6636) New hadoop command to show NameNode
& JobTracker assosiated with client.

Allen Wittenauer commented on HADOOP-6636:
------------------------------------------
A few random comments:
a) mradmin -report is in 21 or 22
b) Both of these *should* report the NN and JT info and it is kind of funny that no one noticed.
c) A separate, unprivileged command makes sense, especially when you consider something like HADOOP-5670 .
d) PLEASE don't make the option camelCase. This is the shell, not Java. The current camelCase options drive me batty as it is. :)

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.
