Anne Yu created SENTRY-855:
------------------------------

             Summary: support DROP ROLE IF EXISTS or CREATE ROLE IF NOT EXISTS
                 Key: SENTRY-855
                 URL: https://issues.apache.org/jira/browse/SENTRY-855
             Project: Sentry
          Issue Type: New Feature
          Components: Service
    Affects Versions: 1.5.0, 1.5.1
            Reporter: Anne Yu


For drop database/table/view, we support syntax such as,

{code}
DROP DATABASE/TABLE/VIEW [IF EXISTS]
{code}

Only for role, there is no support for IF EXISTS,

We might need to consider to add it.
