Subject [jira] Commented: (HADOOP-4151) Add a memcmp-compatible interface for key types
Date Mon, 15 Sep 2008 23:11:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631179#action_12631179
] 

Doug Cutting commented on HADOOP-4151:
--------------------------------------

This looks good to me, although I'd prefer a name like BinaryComparable.  Also, I think the
change to bin/hadoop is from another issue?

> Sometimes it's beneficial to treat types (like BytesWritable and Text) as byte arrays,
agnostic to their type. Adding an interface to tag key types as amenable to this treatment
can permit optimizations and reuse for that subset of types in tools and libraries.
