------------------------------------------
Agree with you on not breaking backward compatibility. Will post a new patch
with the config.
> Warehouse table subdirectories should inherit the group permissions of the

> When the Hive Metastore creates a subdirectory in the Hive warehouse for
> a new table it does so with the default HDFS permissions. Since the default
> dfs.umask value is 022, this means that the new subdirectory will not inherit
> the
> group write permissions of the hive warehouse directory.
> We should make the umask used by Warehouse.mkdirs() configurable, and set
> it to use a default value of 002.
