Subject JobTracker scheduling when there is no locality optimization.
Date Fri, 07 Dec 2012 22:09:23 GMT
How does the JobTracker schedule / assign tasks to open TaskTrackers when
there is no locality constraints (i.e. when some non file input format,
such as DBInputFormat is used).... Is it random? Or can it optimize for IO?
