Description

In hadoop 2.4.0
NM always have 100+ AppLogAggregatorImpl threads running,
Normally,only 20+ containers will running all time,so if there is any issue about the AppLogAggregator leak.
I observe these threads is all waiting,because the logic of code is:
While(If not appFinshed)
Wait(1s);
