Brian Towles commented on SENTRY-1918:
--------------------------------------
I have updated this to SentryStateBank which allows us to do state from any
component we want. It uses binary states right now but we can change this
implementation later if need be.
> NN snapshot should not be served while HMS snapshot is collected

> 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.
