> 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, which can hurt performance.
> 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.
