             Summary: Improve the error handling in setup-ranger
                 Key: IMPALA-10694
                 URL: https://issues.apache.org/jira/browse/IMPALA-10694
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Fang-Yu Rao
            Assignee: Fang-Yu Rao


Currently [setup-ranger()|https://github.com/apache/impala/blob/master/testdata/bin/create-load-data.sh#L329-L388] is used to create the Ranger policy repository to perform authorization-related tests. We found that the error handling in {{setup-ranger()}} could be improved.

For instance, at https://github.com/apache/impala/blob/master/testdata/bin/create-load-data.sh#L385-L387, we update the policy of id equal to 4, which corresponds to the policy of "{{all - database}}". However, it is possible that new default policies are added to the policy repository in newer versions of Ranger. When this occurs, the policy of id equal to 4 may no longer correspond to the policy of "{{all - database}}", resulting in an error returned from the Ranger server. The current implementation of {{setup-ranger()}} would not stop in this case. That is, the pre-commit tests would continue even if the policy repository was not updated correctly, which causes the authorization-related tests to fail later in the pre-commit tests. It would thus be good if we could detect such an error in {{create-load-data.sh}} before any test is run.
