[jira] [Created] (HDFS-4453) Make a simple doc to describe the usage and design of the shortcircuit read feature

Brandon Li created HDFS-4453:
--------------------------------

             Summary: Make a simple doc to describe the usage and design of the shortcircuit read feature
                 Key: HDFS-4453
                 URL: https://issues.apache.org/jira/browse/HDFS-4453
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode, hdfs-client
            Reporter: Brandon Li


It would be nice to have a document to describe the configuration and design of this feature. Also its relationship with previous short circuit read implementation(HDFS-2246), for example, can they co-exist, or this one is planed to replaces HDFS-2246, or it can fall back on HDFS-2246 when unix domain socket is not supported.
