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

[~andrew.wang] I'm surprised that the bugs related Guava cannot be found in unit tests. Anyway,
it's basically okay to back the version of Guava to 0.11.2 because the update of Guava caused
some unexpected behaviour especially like breaking Timeline Server and incompatibility like
YARN-6564. Thanks [~steve_l] for working the topic.

We're now choosing the version of Curator with shaded Guava, so we can safely downgrade the
version of Guava.

> As an alternative to reverting or shading HADOOP-10101 (the upgrade of Guava from 11.0.2
to 21.0), HADOOP-14380 makes the Guava version configurable. However, it still doesn't compile
with Guava 11.0.2, since HADOOP-10101 chose to use the moved Guava classes rather than replacing
them with alternatives.
> This JIRA aims to make Hadoop compatible with Guava 11.0.2 as well as 21.0 by replacing
usage of these moved Guava classes.
