RE: jps problem

Hi Bejoy,
Thanx for ur reply.


My jps command is also failed in datanode.

When I run command on master node:-->(java version is 1.6.32)

[hadoop@NHCLT-PC44-2 bin]$ jps
31791 NameNode
31937 DataNode
1292 Jps
32176 JobTracker
32309 TaskTracker
32086 SecondaryNameNode
[hadoop@NHCLT-PC44-2 bin]$

When I run on datanode:--> (java version is 1.6.35)
[hadoop@NHCLT-PC44-4 ~]$ jps
[hadoop@NHCLT-PC44-4 ~]$

Can you please let me know where I lag?
Regards,
Ajit

Hi Ajit

Is Oracle jdk used in your data nodes? If it is open jdk then I guess jps won't work. Also have you configured java correctly on DNs for the user that issues jps command?

The hive 'GettingStarted' on hive wiki is a good start off. It lets you know which all properties to override in your hive-site.xml.

Hi Nitin,



Thanks for your reply.

I want configuration file of hive with respect to distributed hadoop.



Again My jps command is also failed in datanode.



When I run command on master node:-->



[hadoop@NHCLT-PC44-2 hadoop]$ jps

5694 NameNode

5992 SecondaryNameNode

5843 DataNode

6224 TaskTracker

6085 JobTracker

6701 Jps

4785 RunJar



But when I run the same command on slave node:-->

[hadoop@NHCLT-PC44-4 hadoop]$ jps

-bash: jps: command not found



Can you please help me in this regard.

I am not sure what you mean by distibuted hive.



but a multinode hadoop cluster setup you can setup using following link

http://ankitasblogger.blogspot.in/2011/01/hadoop-cluster-setup.html



if you run into hic-ups feel free to reach me out on my email (dont

want hive userlist to be bugged for hadoop installations)
