CDK-365: Shut down HBase and DFS clusters to fix conflicts.
CDK-365: Add test dependency on thrift 0.9.0.

There is a conflict between the thrift dependency from hbase (0.8.0) in
hadoop-1 and the version from hive (0.9.0). This adds a test dependency
on 0.9.0 that fixes the conflict and allows Travis CI tests to pass.
Long-term, we need to deconflict the hadoop-1 dependencies.
