Review request for sentry, Alexander Kolbasov, Na Li, and Sergio Pena.
Bugs: SENTRY-2115
https://issues.apache.org/jira/browse/SENTRY-2115
Repository: sentry
Description
-------
**Scenario-1:** When HDFS sync is disabled, and sentry is started for the first
time.
**Scenario-2:** When HDFS sync is disabled, and current event-id from HMS is
less than last event-d processed by sentry
**Scenario-3:** When HDFS sync is disabled, and first event-id in the
subsequent pull is not greater than the last event-id processed by sentry by 1.
**New Behavior:** Full snapshots need not be taken in all
When Sentry detects out-of-sync situations, it should reset
SENTRY_HMS_NOTIFICATION_ID table and start processing the event in
HMS_NOTIFICATION_LOG from beginning.
**Scenario-4:** Initially HDFS sync was enabled and later disabled for while
and then HDFS sync is enabled and sentry service is restarted to get it to
effect.
**New Behavior:** When Sentry detects out-of-sync situations, it should reset
SENTRY_HMS_NOTIFICATION_ID table and start processing the event in
HMS_NOTIFICATION_LOG from beginning.
To handle scenario explained in Scenario-4, sentry should reset the mapping
information when ever HDFS sync is disabled. That way it can learn from scratch
when the feature is enabled back. There is no value is holding stale data even
when we know it will have issues when the feature is enabled back.
