[MapReduce-user] is HDFS RAID "data locality" efficient?

: exactly: less space use on cold data, with the penalty that access performance can be worse. As the majority of data on a hadoop cluster is usually "cold", it's a space and power efficient story for the archive data -- Steve Loughran Hortonworks Inc

: I tend to think the only way this is going to 'really' be fixed is one email to all users explaining what's happened re: consolidation, instructions on how to subscribe to the new list, then nuke the whole list and start anew. it might be an extreme response, but I think the number of failing attempts is showing that extreme is what's actually needed. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
