Subject [jira] [Created] (HDFS-5149) Support for federated cache pools
Date Fri, 30 Aug 2013 18:57:53 GMT
Andrew Wang created HDFS-5149:
---------------------------------

             Summary: Support for federated cache pools
                 Key: HDFS-5149
                 URL: https://issues.apache.org/jira/browse/HDFS-5149
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-4949
            Reporter: Andrew Wang
            Assignee: Andrew Wang


The federation concept of a "blockpool" has not pervaded the caching implementation thus far,
e.g. datanodes do not track and report usage by block pool, some namenode operations are not
block pool aware. This requires re-examination of protobufs / protocol / handling throughout.
