IMPALA-7712: Support Google Cloud Storage
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.
