Date Sat, 10 Dec 2011 02:24:41 GMT
Make BlockReaderLocal not extend RemoteBlockReader2
---------------------------------------------------

                 Key: HDFS-2654
                 URL: https://issues.apache.org/jira/browse/HDFS-2654
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 0.23.1, 1.0.0
            Reporter: Eli Collins
            Assignee: Eli Collins


The BlockReaderLocal code paths are easier to understand (especially true on branch-1 where
BlockReaderLocal inherits code from BlockerReader and FSInputChecker) if the local and remote
block reader implementations are independent, and they're not really sharing much code anyway.
If for some reason they start to share sifnificant code we can make the BlockReader interface
an abstract class.
