             Summary: Add pluggable interface for reading replicas in DFSClient
                 Key: HDFS-8924
                 URL: https://issues.apache.org/jira/browse/HDFS-8924
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
    Affects Versions: 2.8.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


We should add a pluggable interface for reading replicas in the DFSClient.  This could be used to implement short-circuit reads on systems without file descriptors, or for other optimizations.
