-------------------------------------
Summary: keep policy-cache snapshot for each update
Key: RANGER-4170
URL: https://issues.apache.org/jira/browse/RANGER-4170
Project: Ranger
Issue Type: Improvement
Components: plugins
Reporter: Xiaomin Zhang
We observed strange issue that plugin is not able to find the correct policy
hence failing the access request. This is intermittent and not reproduced at
will. This issue seems gone after restarting the component or RangerAdmin or
make some slight changes to the affected policy, or just wait for some while
without doing any thing.
Since policy-cache snapshot at the issue time is critical to debug this issue,
but there is a major gap here to keep the snapshot. We need some improvement in
component plugin to keep every policy-cache snapshot when it's updated, so that
we can trace back to find the policy-cache at the point of time when issue
recurs.
