-------------------------------------------------------------
[~conquestor] Hi Minho, there're things must be considered.
{code}
vargs.add(Long.toString(container.getId().getContainerId()));
{code}
Currently it seems task uses dynamic containerID. But, index of tasks must be
sqeuntial number from 0 for instance, task 0, task 1, task 2, ... to support
getPeerIndex() method.
{code}
/**
* @return the index of this peer from sorted array by taskId.
*/
public int getPeerIndex();
{code}
and additionally, if RawSplit has partitionID and it's bigger than -1, taskID
must match to the partitionID. This is used for obtaining “nearby or related”
data based on partitioner.

> ArrayIndexOutOfBoundsException occurs when the number of tasks are greater
