-------------------------------
Summary: Apps that have completed can appear as RUNNING on the NM
UI
Key: YARN-376
URL: https://issues.apache.org/jira/browse/YARN-376
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.0.3-alpha, 0.23.6
Reporter: Jason Lowe
On a busy cluster we've noticed a growing number of applications appear as
RUNNING on a nodemanager web pages but the applications have long since
finished. Looking at the NM logs, it appears the RM never told the nodemanager
that the application had finished. This is also reflected in a jstack of the
NM process, since many more log aggregation threads are running then one would
expect from the number of actively running applications.
