Brandon Li commented on HADOOP-9669: ------------------------------------ Thanks, Haohui. Some comments: 1. please try to keep the original javadoc for the same named methods 2. can you make "State state" as final? 3. please fix the javadoc /** check if the rest of data has more than <len> bytes */ "len" is not visible in generated javadoc 4. readFixedOpaque still has a copy not sure if it's possible to generat a read-only bytebuffer from another bytebuffer 5. it would be nice to remove the extra copy for writeFixedOpaque For 4 and 5, I am ok if you think it's out of scope of this JIRA. > 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 > Components: nfs > Reporter: Tsz Wo (Nicholas), SZE > Assignee: Haohui Mai > Attachments: HADOOP-9669.001.patch, HADOOP-9669.patch > > > 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(..). -- This message is automatically generated by JIRA.
