[jira] [Created] (NIFI-7641) NullPointerException with
ExecuteFlumeSource
Pierre Villard created NIFI-7641:
------------------------------------
Summary: NullPointerException with ExecuteFlumeSource
Key: NIFI-7641
URL: https://issues.apache.org/jira/browse/NIFI-7641
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Pierre Villard
Faced a NPE when using the ExecuteFlumeSource processor. Seems to be when the processor couldn't bind to the port as another processor was already using it.
