> 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.
