Subject [jira] Commented: (HADOOP-6949) Reduces RPC packet size for primitive arrays, especially long[], which is used at block reporting
Date Wed, 23 Feb 2011 18:26:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6949?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998486#comment-12998486

Hairong Kuang commented on HADOOP-6949:
---------------------------------------

Matt, for the version number. I believe that you just need to bump up the RPC version number:
org.apache.hadoop.ipc.Server#CURRENT_VERSION. This should be good enough.

object array ; array type string + array length + (element type string + value)*n
> It would not be needed to specify each element types for primitive arrays.
