May these few things solve the error :-
1. Check through web interface wheteher the namenode, jobtracker,
tasktracker are running or not.
2. Resolve IP-host name binding to edit /etc/hosts file of all nodes.
Insert these lines
IP-addresss hostname
e. g 192.122.0.111 node1
Thanks

This worked at one time, but I now I'm having an issue:
I have a basic python script for testing python/hive. The script just
does a few simple things:
-show tables
-describe [a table]
-select * from [a table] limit 15
The show tables and describe sections are functioning. However, when
it gets to the select command, then the hive server begins to issue:

The problem I believe is the port that it's trying to connect to. My
hdfs namenode is serviced on port 54310.
I tried adding the following setting to hive-site.xml:
<name>fs.default.name</name> <value>hdfs://mysvr:54310</value>
Any other suggestions?
Thanks!
