------------------------------------------------------------------

I've checked Hadoop 3.0.3 has YARN-7190 in it. 

Hadoop 3.1 brought in a bunch of new YARN features. If HBase requires them to 
develop new features, it would make sense to move up to 3.1. 

With my Hadoop hat on, I strive to ensure Hadoop 3.0.x line is stable.

Hadoop 3.1 release line has a bunch of very new YARN features in it. Hadoop 
3.0.x is much better tested IMHO.

> Upgrade our hadoop 3 dependency to 3.1.1

> 3.1.1 is a stable release. And since 3.0.x is not compatible with hbase due 
> to YARN-7190, we should upgrade our dependency directly to 3.1.x line.
