Review request for sentry, Alexander Kolbasov, kalyan kumar kalvagadda, and Na
Li.
Changes
-------
- Fixed unit tests
- Addressed Lina's comments.
Bugs: sentry-1760
https://issues.apache.org/jira/browse/sentry-1760
Repository: sentry
Description
-------
The patch will set the 'requestHmsSnapshot' to TRUE whenever the following
cases are found:
* List of notifications received are different than expected.
This may happen when Sentry has been down or HDFS sync was disabled for a
while (more than 24h),
and the HMS cleared old notifications (older than 24h) not processed by
Sentry causing a gap when retrieving notifications.
* Latest Sentry notification ID processed is bigger than current HMS
notification ID.
This may happen when the HMS DB data was reset or restore from an old
snapshot causing sync issues with Sentry.
New snapshots are persisted with a new generation ID (or image number), so
there's is no need to clean-up older snapshots.
