My moutinode hadoop is running fine but my hive is throwing
java.net.ConnectException: Call to localhost/127.0.0.1:54310 failed on

Thanks Sangeetha.
If I can check http://:50070/dfsnodelist.jsp?whatNodes=LIVE
amlan-laptop is my master .
If it shows ALL data nodes that mean my multi node hadoop is working fine.(I
think)
Now in hive CLI I am getting
java.net.ConnectException: Call to localhost/127.0.0.1:54310 failed on
conn
Ya,What Jeff said is correct.
You should not name different ip's in a common name. Map the Ip's and host
name correctly and try again.
Cheers!

One thing i notice is that /etc/hosts is different on each host: amlan-laptop
is bound to localhost on the master and its bound to a different ip on the
slave. Make the files on both macnes the same.

Thanks MIS.
Can somebody please tell me what is wrong with this.
cat /etc/hosts (on master)
127.0.0.1 localhost amlan-laptop
192.168.1.11dhan
cat /etc/hosts (on slave)
127.0.0.1 localhost dhan
192.168.1.22amlan-laptop
cat conf/masters (on master)
amlan-laptop
cat con
Please have the host-name and ip address mapping in the /etc/hosts file on
both the nodes that are running hadoop cluster.
One more thing : I hope secondary namenode is also running along namenode
but you may have forgot to mention it.
Thanks,
MIS

It seem you did not config your HDFS properly.
"Caused by: java.lang.IllegalArgumentException: Wrong FS:
hdfs://192.168.1.22:54310/tmp/hive-hadoop/hive_2011-02-21_12-09-42_678_6107747797061030113,

To give more context my multinode hadoop is working fine. fs.default.name,
mapred.job.tracker settings are correct.
I can submit job to my multinode hadoop and see output. (One of the node
running namenode,datanode,job tracker , task tracker other running task
tracker and datanode)

Earlier I had hive running on single node hadoop which was working fine. Now
I made it 2 node hadoop cluster. When I run hive from cli I am getting
following error
java.lang.RuntimeException: Error while making MR scratch directory - check
filesystem config (null)
