Tsz Wo (Nicholas), SZE created HADOOP-9669:
----------------------------------------------

             Summary: There are multiple array creations and array copies for a single nfs
rpc reply
                 Key: HADOOP-9669
                 URL: https://issues.apache.org/jira/browse/HADOOP-9669
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Brandon Li


XDR.writeXxx(..) methods ultimately use the static XDR.append(..) for writing each data type.
 The static append creates a new array and copy data.  Therefore, for a singe reply such as
RpcAcceptedReply.voidReply(..), there are multiple array creations and array copies.  For
example, there are at least 6 array creations and array copies for RpcAcceptedReply.voidReply(..).
