Hi Users list,

I did the following scripts for restaring the system.

1.stop-dfs.sh
2.stop-mapred.sh
3.start-dfs.sh
4.start-mapred.sh

master:
hduser@md-trngpoc1:/usr/local/hadoop/bin$ jps
14454 Jps
18207 NameNode
18537 JobTracker
18410 SecondaryNameNode

slave:
hduser@md-trngpoc2:/usr/local/hadoop/bin$ jps
28038 Jps
23199 TaskTracker
23125 DataNode

Here, I am trying to view the hive table, i am not able to view the table,
getting following error



Error:
