hi,
I am answering to my own question thinking this might help someone
facing same problem.
Problem was with my "/etc/hosts" file.
So anyone facing same problem can look into "/etc/hosts" file and make
sure that name of host is same
everywhere e.g. even in hadoop conf files.
For settings hostname and all one can have a look on

Hi,
When running any query except "show tables" I am getting following error:
-----
FAILED: Unknown exception: Error while making MR scratch directory -
check filesystem config (null)

I have reformatted the namenode still I am getting above error.
So, please help me in fixing this problem.
I have set up hadoop in distributed mode.
Relevant configuration is :
------
<property>
<name>hive.exec.scratchdir</name>
<value>/tmp/hive-${user.name}</value>
<description>Scratch space for Hive jobs</description>
</property>
