Alan Gates commented on HIVE-7242:
----------------------------------
dynpart_sort_optimization passes on both trunk and with the patch when I run
it. root_dir_external_table and authorization_ctas are broken on trunk right
now. So I don't believe these test failures are related to this patch.

> Doing an "alter table foo drop partition ('bar=x')" acquired a shared-write
> lock on partition bar=x. It should be acquiring an exclusive lock in that
> case.
