Hello Kurt Deschler, Joe McDonnell, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/18853
to look at the new patch set (#7).
Change subject: IMPALA-10214, IMPALA-10375: Ozone remote file handle caching
......................................................................
IMPALA-10214, IMPALA-10375: 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.
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 tests that
remote caching can be disabled using individual flags.
