Announce: MR3 0.11 released

I am pleased to announce the release of MR3 0.11. The new feature in MR3
0.11 is the support for autoscaling. Autoscaling works on both Hadoop and
Kubernetes.

I have added a quick start guide on running Hive on MR3 on Amazon EKS with
autoscaling. Autoscaling on Amazon EKS (which uses Kubernetes Autoscaler)
is much faster than on Amazon EMR. For example, on EKS, a scale-out
operation takes about 2 minutes to attach a new node, and a scale-in
operation takes slightly longer than 1 minute to retire an existing node.
In contrast, on EMR, the user should wait at least 5 minutes to trigger
scale-in/out. So if you would like to try autoscaling with Hive on MR3, we
suggest EKS instead of EMR.
