Brian Towles commented on SENTRY-1918:
--------------------------------------
Im going to add a function to the SentryService in order to pass through a
check to the HMSFollower if a FullSnapshot is running. As well the
DBUpdateForwarder will check the SentryService (getting it from changes to the
SentryServiceFactory) to see if the Full Snapshot is running before returning a
full snapshot. If a Full Snapshot is running then it will return an empty
result until the full snapshot is done.
> NN snapshot should not be served while HMS snapshot is collected

> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.0.0
> Reporter: Alexander Kolbasov
> Assignee: Brian Towles
>
> While Sentry collects full HMS snapshot, Namenode still sends requests to
> sentry and may request a full snapshot which is useless because a new one
> will be available shortly. It is important to prevent this from happening so
> that we do not collect two snapshots in memory at the same time.
