> I used the 0.0.1 minifi converter toolkit for a flow containing a GetFile processor with default "Filter Filter" properties ([^\.].*). It generated the following config:
> - name: GetFile
>   class: org.apache.nifi.processors.standard.GetFile
>   max concurrent tasks: 1
>   scheduling strategy: TIMER_DRIVEN
>   scheduling period: 1 sec
>   penalization period: 30 sec
>   yield period: 1 sec
>   run duration nanos: 0
>   auto-terminated relationships list: []
>   Properties:
>     Batch Size: '10'
>     File Filter: '[^\.].*'
>     Ignore Hidden Files: 'true'
>     Input Directory: /host-data/metrics
>     Keep Source File: 'false'
>     Maximum File Age:
>     Maximum File Size:
>     Minimum File Age: 10 sec
>     Minimum File Size: 0 B
>     Path Filter:
>     Polling Interval: 0 sec
>     Recurse Subdirectories: 'true'
> However, at runtime, minifi gives an invalid regex error:
> [2016-10-03 16:31:11.318] [minifi log] [error] Invalid File Filter regex: regex_error.
