----------------------------------
Summary: LocalFlinkMiniCluster leaks resources when multiple jobs
are submitted
Key: FLINK-3266
URL: https://issues.apache.org/jira/browse/FLINK-3266
Project: Flink
Issue Type: Bug
Components: Local Runtime
Affects Versions: 1.0.0
Reporter: Gabor Gevay
Priority: Minor
After a job submitted to a LocalEnvironment finishes, some threads are not
stopped, and are stuck in waiting forever.
You can observe this, if you enclose the body of the main function of the
WordCount example with a loop that executes 100 times, and monitor the thread
count (with VisualVM for example).
(The problem only happens if I use a mini cluster. If I use start-local.sh and
submit jobs to it, then there is no leak.)
