-----------------------------------
Summary: PostHTTP and ListenHTTP never shutdown
LeakyBucketStreamThrottler thread
Key: NIFI-1865
URL: https://issues.apache.org/jira/browse/NIFI-1865
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.4.1
Reporter: Koji Kawamura
Priority: Minor
LeakyBucketStreamThrottler implements close and inside it it shutdowns
executorService.
However, ListenHTTP and PostHTTP doesn't call close, and since those processors
create new LeakyBucketStreamThrottler instance when it is scheduled, it creates
new thread without closing the old ones.
It can be reproduced by repeating stop and start those processors again and
again. You can confirm the number of threads are increasing by following
command:
{code}
$ watch "ps -M |grep {nifi pid} | wc -l"
{code}
or using thread dump
{code}
$ tail -f logs/nifi-bootstrap.log |grep LeakyBucketStreamThrottler.java
from another terminal
$ kill -3 {nifi pid}
{code}
