Subject: [PATCH] [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
EDIT: Adding yhuai who worked on the relevant classloading isolation pieces.
Author: Dennis Huo <dhuo@google.com>
Closes #7549 from dennishuo/dhuo-fix-hivecontext-gcs and squashes the following commits:
