Mark Payne created NIFI-916:
-------------------------------
Summary: NiFi stop command occasionally results in Socket Timeout
exception
Key: NIFI-916
URL: https://issues.apache.org/jira/browse/NIFI-916
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Fix For: 0.3.0
When I issue the bin/nifi.sh stop command, running in CentOS 7 in my VM, I
occasionally get a timeout exception. If this happens, it will continue to
happen until I manually kill the process.
Below is the output that I receive, as well as the results of running netstat
to verify that NiFi is in fact listening on the port reported.
