Subject [jira] [Updated] (HADOOP-15872) ABFS: Update to target 2018-11-09 REST version for ADLS Gen 2
Date Wed, 24 Oct 2018 22:20:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15872?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Marquardt updated HADOOP-15872:
--------------------------------------
    Description: 
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.
