Subject [jira] [Commented] (HADOOP-7557) Make IPC header be extensible
Date Fri, 07 Oct 2011 20:00:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123130#comment-13123130
] 

Steve Loughran commented on HADOOP-7557:
----------------------------------------

One thing I'd like to see is IPC messages including a CRC32 checksum, to compensate for the
limitations of the TCP checksum. Ideally it should go as a footer (some papers argue for this
in terms of creation, validation and to catch two messages merged to each other. If a footer
can't be done, it would be nice to somehow sneak in the checksum here. Would that be possible?
