Vladimir Ozerov updated IGNITE-2886:
------------------------------------
Fix Version/s: (was: 1.7)
> IGFS: Implement INotify intergration.
> -------------------------------------
>
> Key: IGNITE-2886
> URL: https://issues.apache.org/jira/browse/IGNITE-2886
> Project: Ignite
> Issue Type: Task
> Components: hadoop, IGFS
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Assignee: Oddo
> Priority: Critical
>
> The idea is originally proposed by Michael Pearce on the dev-list: http://apache-ignite-developers.2346864.n4.nabble.com/HDFS-iNotify-td8033.html
> Currently IGFS is unable to deal with changes performed on HDFS directly. That is, all file system operations must go through IGFS to maintain integrity of in-memory file system view.
> This appears to be a known issue with other Hadoop-based integrations. HDFS has relatively new interface {{INotify}} which allows callbacke to external sources when file system is updated. We need to evaluate possibility integrate IGFS with this module.
