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

             Summary: Implement packet memory pool in output stream in libhdfs3
                 Key: HDFS-7445
                 URL: https://issues.apache.org/jira/browse/HDFS-7445
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs-client
            Reporter: Zhanwei Wang
            Assignee: Zhanwei Wang


Implement a packet memory pool instead of allocating packet dynamically. A packet memory pool can guard against overcommit and avoid the cost of allocation for output stream in libhdfs3.
