---------------------------
Summary: FetchFileTransfer erroneously alters Destination
Directory when performing COMPLETION_STRATEGY
Key: NIFI-9196
URL: https://issues.apache.org/jira/browse/NIFI-9196
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.14.0
Environment: MS Windows 10 Version 20H2 (compilation 19042.1165)
Java SE Runtime Environment (build 16.0.1+9-24)
Connecting to a remote SFTP server (OpenSSL)
Reporter: Layon
Attachments: Capture.PNG
Scenario:
NiFi running on windows
# FetchSFTP processor reads files from a remote SFTP server *(ok)*
# FetchSFTP then is configured to perform a "completion strategy" of moving
the fetched files to another remote directory *(fails)*
It was found that FetchSFTP (who extends FetchFileTransfer) alters the property
"Move Destination Directory"
Example:
* Source Remote file: /sftp/file1.txt
* Move Destination Directory: /sftp/done
* Intended file after move: /sftp/done/file1.txt
* After execution, is is found that FetchSFTP sent the SFTP to rename the file
to: {color:#FF0000}C:\sftp\done\file1.txt{color}, so the SFTP server rejects
the operation. The correct path to send is: /sftp/done/file1.txt
Error appears to be in the following code:
* Class: org.apache.nifi.processors.standard.FetchFileTransfer
* method: performCompletionStrategy
* Line: transfer.rename(flowFile, filename,
targetFile.get{color:#FF0000}Absolute{color}Path());
** Correct method to call appears to be targetFile.getPath()
