---------------------------------------
Summary: LocalFS to support ability to disable permission get/set;
remove need for winutils
Key: HADOOP-17839
URL: https://issues.apache.org/jira/browse/HADOOP-17839
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Affects Versions: 3.3.1
Reporter: Steve Loughran
Setting FS permissions on windows has always been a paint point for people
running spark standalone, creating files through localFS required WINUTILS.EX
To do this
I'm seeing some other demand for disabling setting permissions, primarily
because if you mount storage (including azure storage) to a VM, you cant call
setPermissions; things fail.
Proposed:
1. we add an option to disable permission setting
2. we add a path capability, which for hdfs, abfs is always true (not sure
about wasb as it varies on file vs dir)
3. we add the option to turn off permission get/set for RawLocalFileSystem and
downgrade to a no-op on write, ug+rw on read (or even make configurable?)
(Distcp should maybe probe the path and downgrade -p options if the dest store
doesn't do perms properly, which argues for wasb to return true, so file perms
are set)
