Please recheck your cluster once, whether all the places has the same evrsion of Jars. It looks RPC client and servers are different versions. ________________________________________ From: Nitin Khandelwal [nitin.khandel...@germinait.com] Sent: Monday, November 28, 2011 5:32 PM To: common-user@hadoop.apache.org Subject: 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, -- Nitin Khandelwal
