--------------------------------

             Summary: NFS should create input stream for a file and try to share it with multiple read requests
                 Key: HDFS-5171
                 URL: https://issues.apache.org/jira/browse/HDFS-5171
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: nfs
            Reporter: Brandon Li
            Assignee: Brandon Li


Currently, NFS creates an input steam for each read request and closes it after the request is served. With lots of read request, the overhead is significant. 

Like for write request, NFS should create input stream for a file and try to share it with multiple read requests. The stream can be closed if there is no read request for a certain amount of time (e.g., 10 sec).
