Sergio Peña commented on SENTRY-1760:
-------------------------------------
What cases should be considered as gaps between notifications? Probably:
- Notifications that could not be processed due to errors.
- HDFS sync is disabled.
- Other ones?
Btw, I see in the HMSFollower code this:
{noformat}
if (!eventIDBefore.equals(eventIDAfter)) {
LOGGER.error("#### Fail to get a point-in-time hive full snapshot !!
Current NotificationID = " +
eventIDAfter.toString());
return;
}
{noformat}
What's the expected behavior? Does the user need to restart Sentry on the above
situation? or should HMSFollower handle that; sleep and redo the initial
snapshot automatically?
> HMSFollower should detect when a full snapshot from HMS is required

> The current criteria for getting a full snapshot from HMS is insufficient. We
