Hi,
The (o.a.h.fs) FileSystem API has GetBlockLocations that is used to determine
replicas.
In general cases, (o.a.h.mapreduce.lib.input) FileInputFormat's getSplits()
calls this method, which is passed on for job scheduling along with the split
info.
Hope this is what you were looking for.

Hi,
Can you provide info on the input like compression etc? Also, are you using
cached files in your map tasks? It might be helpful if you paste the logs here
after blanking your system specific info., as then one can find out where till
the reduce it went or if the copy phase started at all.

And the combiner runs while fetching the outputs right?
