Much like the user commenting at the bottom of https://issues.apache.org/jira/browse/NIFI-4074 I can't figure out how to use the File Filter regex. For example if I want to recursively find every file ending in .bat under the hdfs director /data I would use the regex ".*\.bat" however that doesn't appear to work and the ListHDFS Processor returns nothing. This is in the Hortonworks HDF 3.1.2 release of NiFi 1.5. The tool tip seems to indicate the regex is only applied to the file name so what am i missing.
Thanks Shawn Weeks
