Sorry for the late response, this week has been a bit crazy. I updated the
processor to add all the suggestions (except the filtering update you talked
about). I will look into updating the way the processor does filtering, but I
have a couple concerns. For example, the comma-separated list of paths won't
always work. HDFS directories can technically have commas. Also, I couldn't
find an example of how regular expressions work with the expression language.
I'm a but curious how'll they'll interact with one another. I'll try to find
some time to play around with it this weekend to see.

> Key: NIFI-1037
> URL: https://issues.apache.org/jira/browse/NIFI-1037
> Project: Apache NiFi
> Issue Type: New Feature
> Reporter: nicolas maillard
> Assignee: Josh Meyer
> Priority: Minor
>
> HDFS has an Inotify interface that enables to access the HDFS edit stream.
> https://issues.apache.org/jira/browse/HDFS-6634
> Creating a processor to listen in and get notifications either for select
> directories or select actions would have many applications.
> - Stream to a search engine the activity on HDFS
> - Wait for specific actions or files to trigger workflows, like duplication
> to other clusters
> - Validate ingestion processes
> etc..
> probably more I don't think of.
> I have a first working beta version that needs to evolve
> it reuses the Hadoop-nar-bundle
> Needs a HDFS 2.7 dependency currently done through editing the Hadop-lib
> bundle
> let me know if this idea makes sense and would be of interest to the community
> would love to contribute the idea
