> I propose add second type of predicate after "file.exist" - "custom". JSON
> example for creation "custom" predicate
> {code:java}
> {
> "type": "custom",
> "config": {
> "class":
> "org.apache.griffin.core.job.FileExistPredicator",
> "root.path": "/path/to/",
> "path": "file.ext,file2.txt"
> }
> }
> {code}
> Proposed contract for implementations is based on FileExistPredicator:
> * class must implement interface *org.apache.griffin.core.job.Predicator*
> * class must have constructor with argument of type
> *org.apache.griffin.core.job.entity.SegmentPredicate*
