Hi,
Thanks for your reply. I have a small test table which has around 10 records.
when i run select * from table.. it launched a job and that got completed
successfully. When i run the same query in my actual table no job got
initiated. it got struck. I did not get any error in my task tracker also. All
my data nodes are up and running.
I don't have any clue here.
Thanks,

when you run select * from table .. it does not launch a mapreduce job,
where are when you put some condition, it does need to process the data so it
launches a mapreduce job
now when you start this query, go to your jobtracker page and see how many jobs
are running. Is it able to start your job? if not why ? that will tell you why
its stuck

Hi,
If i run a hive query like "select * from table_name limit 10" it is working.
If i run query like "select column_name from table_name limit 10" it hangs.
Total MapReduce jobs = 1
Launching Job 1 out of 1Number of reduce tasks is set to 0 since there's no
reduce operator
It just prints the above after that nothing happening in the hive shell.
Can you pls help me on this.
Thanks,
