[SPARK-9206] [SQL] Fix HiveContext classloading for GCS connector.
IsolatedClientLoader.isSharedClass includes all of com.google.\*, presumably
for Guava, protobuf, and/or other shared Google libraries, but needs to
count com.google.cloud.\* as "hive classes" when determining which
ClassLoader
to use. Otherwise, things like HiveContext.parquetFile will throw a
ClassCastException when fs.defaultFS is set to a Google Cloud Storage
(gs://)
path. On StackOverflow: http://stackoverflow.com/questions/31478955
