Hi Tariq,
It is a very simple query like select * from table. Actually i've moved my
masternode node from one server to another. I copied all the hadoop temp files
and dfs data directory. Then i installed hive in the same machine and
configured. i'm getting exception while executing the query it throws error.
will it create any problem here?
Thanks,

tables are working fine. Queries with map reduce is throwing exception.
