      Description

      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.
