Subject Mapping from JobSplit to Blocks on datanodes
Date Mon, 28 Nov 2011 07:17:01 GMT
Hi,

How can I find which Job Split does a Block on a datanode belong to? Or
going the other way, if I can find how a Job Split is eventually stored on
datanodes i.e. the list of Blocks.
Any pointers are appreciated.

PS: My eventual objective is 'moving data to computation' (for some
experiments) and hence was taking ideas from Balancer class to move blocks.

Regards
Lokendra
