Subject [jira] [Commented] (HDFS-6634) inotify in HDFS
Date Wed, 09 Jul 2014 17:21:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6634?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14056474#comment-14056474

James Thomas commented on HDFS-6634:
------------------------------------

That would require this project to be a third-party service, much like the work presented
in http://www.youtube.com/watch?v=7KumMKqBtr8

So I think the same concerns raised in the Q & A (starting around 25:30) would apply here
-- in particular, changes to the format of the audit log would cause problems for user applications.
I think tighter integration with HDFS and exposure of the edits in ProtoBuf form is important.
