Otto Fowler updated METRON-534:
-------------------------------
Attachment: inotify-ascii.png
> Metron Should have service to monitor HDFS for changes to files
> ---------------------------------------------------------------
>
> Key: METRON-534
> URL: https://issues.apache.org/jira/browse/METRON-534
> Project: Metron
> Issue Type: New Feature
> Reporter: Otto Fowler
> Priority: Minor
> Attachments: inotify-ascii.png
>
>
> With the INotify library it is possible to receive notifications from HDFS on
> file changes.
> A service that utilized this and was configured with "rules" to process
> notifications on files of interest ( configurations, rules etc ) in the
> system would be able to send notifications to Zookeeper
> This may allow for things that are better stored in HDFS to remain there, and
> not force the system to put things in Zookeeper just for change
> notifications.
> Issues:
> * Inotify requires hdfs super user, what are the implications on a secure
> cluster etc?
> * performance / scalability and load
> * Can it be deployed with yarn?
> * Is Zookeeper actually the right place for all the configurations
