Subject [jira] [Commented] (HIVE-16346) inheritPerms should be conditional based on the target filesystem

Pengcheng Xiong commented on HIVE-16346:
----------------------------------------

Hello, I am deferring this to Hive 3.0 as we are going to cut the first RC and it is not marked
as blocker. Please feel free to commit to the branch if this can be resolved before the release.

> Right now, a lot of the logic in {{Hive.java}} attempts to set permissions of different
files that have been moved / copied. This is only triggered if {{hive.warehouse.subdir.inherit.perms}}
is set to true.
> However, on blobstores such as S3, there is no concept of file permissions so these calls
are unnecessary and can could a performance impact.
> One solution would be to set {{hive.warehouse.subdir.inherit.perms}} to false, but this
would be a global change that affects an entire HS2 instance. So HDFS tables will no longer
have permissions inheritance.
> A better solution would be to make the inheritance of permissions conditional on the
target filesystem.
