Problem running Hadoop 0.23.0

Hi,

I was trying to setup Hadoop 0.23.0 with help of
http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/SingleCluster.html.
After starting resourcemanager and nodemanager, I get following error when
i try to hit Hadoop UI "*ÿÿÿÿÿÿÿÿ���)org**.apache.hadoop.**ipc.RPC$Version**
Mismatch���>Ser**ver IPC version 5 cannot communicate with client version 47
*".
There is no significant error in Hadoop logs (it shows everything started
successfully).

Do you have any idea about this error?

Thanks,

Please recheck your cluster once, whether all the places has the same evrsion of Jars.
It looks RPC client and servers are different versions.

Hi Nitin,

It looks like you may be using the wrong port number - try 8088 for
the resource manager UI.

Cheers,
Tom
