Sivaprasanna Sethuraman commented on NIFI-5152:
-----------------------------------------------
I have made the necessary changes to the onTrigger() to have MoveHDFS work even
when no upstream connection is provided. Also made `INPUT_DIRECTORY_OR_FILE`
PropertyDescriptor as required.
> MoveHDFS should have @InputRequirement(Requirement.INPUT_REQUIRED)

>
> The onTrigger method of MoveHDFS will return when no incoming flow file is
> obtained, therefore the processor can only be used with an incoming
> relationships and should have the INPUT_REQUIRED annotation.
> If the expected behavior was to use the processor without an incoming
> relationship, then instead of requiring input, the code needs to be updated
> to handle both scenarios.
