Review comment:
The `Directory` property indicates support for FlowFile Expression
Language, which means that `getProperty()` needs to call
`evaluateAttributeExpressions(FlowFile)`. Since the FlowFile is not available
in this method, it looks like a different approach is necessary.
One option is implementing this hook through a method called from
`onTrigger()`, but that would log a warning for every invocation of the
Processor.
Since the only current purpose of this hook is to log a warning, this may
not be the best approach to the issue. Perhaps adding a note to the umask
property would be a better option?
