Subject Find Input for specific Map-Task/Reduce Task
Date Fri, 06 Jan 2012 12:54:32 GMT
Hi All,

I am using hive 0.7 version.
I want to know if it is possible to find the input records for a particular
map task or a reduce task.

I need it because my map-reduce job creates around 30 reduce tasks and one
of it is failing while rest of the 29 get completed successfully. If I can
get the input data for this reduce task, it will greatly reduce the
debugging effort required.

Thanks in Advance

Best Regards,
