Subject [jira] Commented: (HADOOP-5528) Binary partitioner
Date Fri, 20 Mar 2009 16:40:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683930#action_12683930
] 

Owen O'Malley commented on HADOOP-5528:
---------------------------------------

I don't see the issue. How is it different specifying:

offset = 1
length = 5

rather than

left = 1
right = 6

Am I missing something?

> It would be useful to have a {{BinaryPartitioner}} that partitions {{BinaryComparable}}
keys by hashing a configurable part of the bytes array corresponding to each key.
