I have created a process in Nifi to get a file from a first folder, compress it and delete the uncompressed file. I have used: GetHDFS: to get the file, deleting it from the folder (Keep Source File is set to False) PutHDFS: to compress the file and save in a second folder The process seems working, in fact the file is not anymore in the first folder and the compressed file is in the second folder. The problem is that a warning message is displayed: Could not remove <file path> from HDFS. Not ingesting this file... So I have the doubt that the uncompressed file is still somewhere in the HDFS, but I don't know where. What does it mean the warning message?
