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.
