Subject [jira] [Created] (HDFS-5194) Robust support for alternate FsDatasetSpi implementations
Date Thu, 12 Sep 2013 21:31:52 GMT
David Powell created HDFS-5194:

             Summary: Robust support for alternate FsDatasetSpi implementations
                 Key: HDFS-5194
                 URL: https://issues.apache.org/jira/browse/HDFS-5194
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode, hdfs-client
            Reporter: David Powell
            Priority: Minor

The existing FsDatasetSpi interface is well-positioned to permit extending Hadoop to run natively
on non-traditional storage architectures.  Before this can be done, however, a number of gaps
need to be addressed.  This JIRA documents those gaps, suggests some solutions, and puts forth
a sample implementation of some of the key changes needed.
