Any pointers please ? I could see from the source says that it is not trivial to do. Was just wanted to confirm if there are some API calls I might have missed. Regards Lokendra On Mon, Nov 28, 2011 at 2:17 AM, Lokendra Singh wrote: > Hi, > > How can I find which Job Split does a Block on a dat

Mapping from JobSplit to Blocks on datanodes

2011-11-27 Thread Lokendra Singh
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)
