      Description

      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.
