-----------------------------
Summary: Source processors should not delete source file by default
Key: NIFI-10420
URL: https://issues.apache.org/jira/browse/NIFI-10420
Project: Apache NiFi
Issue Type: Wish
Reporter: Martin
The default behaviour of source processors that are retrieving files (GetFile,
GetSMB, GetFTP, GetSFTP) is to delete the original file. This can lead to
unwanted consequences if a data flow manager is debugging or creating new flows
and using the default value. Some cases:
* If the DFM configured a hostname, username and password and need to assert
that the connection to a remove server is ok. If the DFM does not change the
default behaviour of the source files, all files may be deleted.
* If the DFM is applying a reference parameter to the source file
perseverance, and click "Go to reference parameter" to change the parameter
value without applying changes to the source processor first, then the
reference to the parameter is not saved, and the DFM may be lead to believe
that the processor is using the parameter.
