-Re: How to prevent user drop table in Hive metadata?
Shreepadma Venugopalan 2013-11-22, 22:36
Apache Sentry (incubating) provides fine-grained role-based authorization
for Hive among other components of the Hadoop ecosystem. It currently
supports fully secure, fine-grained, role-based authorization for Hive and
can be used to prevent the scenario described earlier i.e., prevent a user
from dropping a table the user shouldn't be allowed to drop.
