-------------------------------------------------------------

I'm good. let's add this to the 0.5 roadmap.

P.S., I don't want to seriously considering about advanced scheduling now, But to handle bulk
synchronous task scheduling problem efficiently, all things considered, we'll need to separate
the phases into data loading phase, data re-distribution/re-partition phase, BSP computation
phase, and output writing phase.

I think, the HAMA-531 and recovery issues ( http://markmail.org/thread/2o625g2pqrtolizi#query:+page:1+mid:ltazto7k2wapshxs+state:results
)are all basically an extension of this.

> Currently, BSP Task is not scheduled on the host that has the input split stored by HDFS.
BSP Task scheduler should make an attempt to start the task on the host that has the input
split located on it.
