Subject Split locations
Date Wed, 07 Mar 2012 13:57:28 GMT

In MapReduce, if the locations of the split are in {HostA, HostB, HostC},
and the respective map tasks will run in HostB, the map tasks will pick up
the split from HostB?

Who is responsible to make the map tasks get the spilt in HostB? Is the
JobTracker or the MapTask?

Best regards,
