Thanks @ijokarumawak ! Got this merge to master.
> Make PutSFTP 'Disable Directory Listing' a normal property
> ----------------------------------------------------------
>
> Key: NIFI-4694
> URL: https://issues.apache.org/jira/browse/NIFI-4694
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
> Priority: Minor
> Fix For: 1.5.0
>
>
> PutSFTP checks dir existence and if not, it tries to create the dir. Since
> it's done by these two operations, if any other SFTP client (other thread,
> other NiFi node in the same cluster or whatever) created the same dir between
> checking and creating dir, it's possible to get an Exception.
> Actually, above error can be avoided, by a dynamic property named 'Disable
> Directory Listing'. If set to 'true', then the processor won't perform
> directory existence check. It will just perform create dir operation blindly
> and swallow an Exception if thrown.
> The property has been a dynamic property, but it should be a normal property
> so that users can notice the option.
