> HADOOP-11492 upped the Curator version to 2.7.1, which makes the
> {{ChildReaper}} class use a method that only exists in newer versions of
> Guava (we have 11.0.2, and it needs 15+). As a workaround, we can copy the
> {{ChildReaper}} class into hadoop-common and make a minor modification to
> allow it to work with Guava 11.
> The {{ChildReaper}} is used by Curator to cleanup old lock znodes. Curator
> locks are needed by YARN-2942.
