Assuming you have your own internal beta-test endpoint: can you confirm that with this patch in, all of the abfs tests completed successfully?

> This update to the latest REST version (2018-11-09) will make the following changes to the ABFS driver:
> 1) The ABFS implementation of getFileStatus currently requires read permission. According to HDFS permissions guide, it should only require execute on the parent folders (traversal access). A new REST API has been introduced in REST version "2018-11-09" of ADLS Gen 2 to fix this problem.
> 2) The new "2018-11-09" REST version introduces support to i) automatically translate UPNs to OIDs when setting the owner, owning group, or ACL and ii) optionally translate OIDs to UPNs in the responses when getting the owner, owning group, or ACL. Configuration will be introduced to optionally translate OIDs to UPNs in the responses. Since translation has a performance impact, the default will be to perform no translation and return the OIDs.
