Subject Cluster wide atomic operations
Date Sat, 27 Oct 2012 03:07:16 GMT
How can we manage cluster-wide atomic operations? Such as maintaining an
auto-increment counter.

Does Hadoop provide native support for these kinds of operations?

An in case ultimate answer involves zookeeper, I'd love to work out doing
this in AWS/EMR.
