---------------------------------

             Summary: PutFile should attempt to replace files atomically
                 Key: NIFI-3583
                 URL: https://issues.apache.org/jira/browse/NIFI-3583
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.1.1, 0.7.1
         Environment: On Windows, NIO2's Files.move operation may not allow 
atomic file replacement, in which case it would have to fall back to the 
existing method.
            Reporter: Eugene Hart
            Priority: Trivial


A PutFile configured with the "replace" conflict resolution strategy will first 
delete any existing file and then move the new temporary file into place. This 
causes there to be a small period of time where the file does not exist at all. 
This could cause problems with other processes relying on this file to always 
exist.
