Correct version on repository-hdfs Guava dependency

This commit sets the version on the repository-hdfs Guava dependency to
version 11.0.2. This change is made to align the version here with the
version that is defined in the POM for Hadoop 2.7.1, the version of
Hadoop that the repository-hdfs plugin is based on. See HADOOP-10101 and
HADOOP-11319 for the ridiculous history of trying to upgrade Guava past
this version in the Hadoop project.
