[jira] [Commented] (CASSANDRA-3137) Implement wrapping
intersections for ConfigHelper's InputKeyRange
[ https://issues.apache.org/jira/browse/CASSANDRA-3137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099084#comment-13099084 ]
Jonathan Ellis commented on CASSANDRA-3137:
-------------------------------------------
Wrapping (key) ranges was the source of a ton of bugs in the 0.6 era. Thus I'm leery of adding wrapped range support to Hadoop just "because we can." Is there a compelling motivation otherwise?
