--------------------------------
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).
