Change subject: IMPALA-10214: Ozone remote file handle caching ...................................................................... IMPALA-10214: Ozone remote file handle caching Enables support for caching remote file handles for Ozone. Local file handles were already cached unintentionally, similar to HDFS. Updates file handle cache enablement to be more stringent about enabling caching, similar to what's suggested in IMPALA-10375. File handle caching is enabled if a max_cached_file_handles is non-zero and any of the following are true - HDFS file is local - HDFS file is remote and cache_remote_file_handles is enabled - Ozone file is local or remote and cache_ozone_file_handles is enabled - S3 file is remote and cache_s3_file_handles is enabled - ABFS file is remote and cache_abfs_file_handles is enabled Enables testing Ozone in test_hdfs_fd_caching, and adds a test that remote caching can be disabled using individual flags.
