Subject Which datanode serves the data for MR
Date Mon, 09 May 2011 07:43:08 GMT
Hi all,

I wanted to know details such as "In an MR job, which tasktracker
(node-level) works on data (inputsplit) from which datanode (node-level) ?"
Can some logs provide data on it? Or do I need to print this data - if yes,
what to print and how to print ?

Thanks,
Matthew
