[jira] [Created] (IGNITE-2886) IGFS: Implement INotify intergration.

Anton Vinogradov (Jira)

---------------------------------------

             Summary: 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
            Priority: Critical
             Fix For: 1.7


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.
