Subject [jira] [Commented] (HADOOP-7824) Native IO uses wrong constants almost everywhere
Date Wed, 22 Jul 2015 09:44:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14636604#comment-14636604
] 

Alan Burlison commented on HADOOP-7824:
---------------------------------------

I suggested to Martin that an array of structs would be easiest way of doing this as it avoids
lots of cut+paste boilerplate - doing it as explicit code would be 280 lines rather than the
100 or so the current mechanism uses. Plus having it table-driven means it's only a small
step to make this code reusable by any Hadoop component that needs to do the same thing.
