This patch adds support for GCS(Google Cloud Storage). Using the gcs-connector, the implementation is similar to other remote FileSystems. New flags for GCS: - num_gcs_io_threads: Number of GCS I/O threads. Defaults to be 16. Follow-up: - Support for spilling to GCS will be addressed in IMPALA-10561. - Support for caching GCS file handles will be addressed in IMPALA-10568. - test_concurrent_inserts and test_failing_inserts in test_acid_stress.py are skipped due to slow file listing on GCS (IMPALA-10562). - Some tests are skipped due to issues introduced by /etc/hosts setting on GCE instances (IMPALA-10563). Tests: - Compile and create hdfs test data on a GCE instance. Upload test data to a GCS bucket. Modify all locations in HMS DB to point to the GCS bucket. Remove some hdfs caching params. Run CORE tests. - Compile and load snapshot data to a GCS bucket. Run CORE tests.
