I want to get exact time spent to spill a map output into disk.
Especially, the time spent to flush method in MapTask.java
It actually easy job when I use a pseudo-distributed mode, but
In real cluster, I tried to use custom counter in MapTask and ReduceTask, it
Also, stdout isn't working.
So, I want you ask about above issues.
