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

             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(..).
