Key: YARN-6295
URL: https://issues.apache.org/jira/browse/YARN-6295
Project: Hadoop YARN
Issue Type: Bug
Components: log-aggregation
Affects Versions: 2.4.0
Reporter: Feng Yuan
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);
