Hi [~joewitt],

To continue with the above, should I merge it anyway ?

> Following flow was setup
> get file -> extract text -> delete hdfs
> A bunch of files were written each having one line which was the path to 
> delete. Some of these path's were files, some were directories and some were 
> patterns. Extract text would extract the line and assign to an attribute 
> which delete hdfs would use to populate the path to delete.
> However the processor would run into an error when ever it tried to process 
> the path which was a pattern matching multiple paths.
