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

Hi [~ozawa] and everyone thanks for the work here.
if we really want to get this into beta1, we'll need to really push harder.

> HADOOP-10101 upgraded the guava version for 3.x to 21.
> Guava is broadly used by Java projects that consume our artifacts. Unfortunately, these projects also consume our private artifacts like {{hadoop-hdfs}}. They also are unlikely on the new shaded client introduced by HADOOP-11804, currently only available in 3.0.0-alpha2.
> We should shade Guava everywhere to proactively avoid breaking downstreams. This isn't a requirement for all dependency upgrades, but it's necessary for known-bad dependencies like Guava.
