MR3 1.2 released

Hello Hive users,

MR3 1.2 has been released. A few improvements in this release are:

1. MR3 can publish Prometheus metrics.
2. On Kubernetes, the user can change the total resources for workers
dynamically (e.g., by using Prometheus metrics). This feature can be
combined with autoscaling in order to further improve resource utilization.
3. Hive on MR3 can run on AWS Fargate. This can be useful when running
queries sporadically.
4. LLAP I/O with NVMe caching works properly, which is particularly useful
on Amazon EKS.
5. Ranger 2.0.0 and 2.1.0 are supported.

For details of changes, please see the release notes in MR3docs:
