marco polo created NIFI-4609:
--------------------------------
Summary: RemoteSiteListener creates and starts worker threads
without bound.
Key: NIFI-4609
URL: https://issues.apache.org/jira/browse/NIFI-4609
Project: Apache NiFi
Issue Type: Bug
Reporter: marco polo
Assignee: Mark Payne
MiNiFI C++ will continually attempt to reconnect to a NiFi instance. In
RemoteSiteListener if something happens to the connection the thread does not
appear to go away and it is unbounded. So if you had many connections come in,
thread.start will create n threads without bound. This was experienced on an
RPI where something happened to the connection and we abandoned it on MiNiFi
C++. Since we don't have insight into what's occurring on the server side we
make an attempt to reconnect, thus creating a new Thread.
Might suggest an ExecutorService to coordinate these threads and potentially an
AfterExecute to perform some accounting for visibility.
