I ran into kind of a weird issue with the ListFile processor. I was referencing a variable for my input directory and had enter the variable name incorrectly.
So I assumed that the with my incorrect variable name the value of the Input Directory would be null or an empty string. When I started the InputFile it started listing all the files inside of my Nifi install directory. Things got bad when the my FetchFile started to delete them. I'm on 1.9.1 but I was wondering if this was the normal behavior or some kind of bug. If anyone has seen this behavior and has some kind of viable workaround please let me know.
