Yes, the issues are related and the proposed solutions will complement each
other. For many, it may not be acceptable to silently serve incomplete data and
would rather prefer to be notified.
In such cases, moving the region offline and raising some sort of alarm which
users can monitor would be preferable.

> As described in HBASE-9737, a corrupt HFile in a region could lead to an
> assignment storm in the cluster since the Master will keep trying to assign
> the region to each region server one after another and obviously none will
> succeed.
> The region server, upon detecting such a scenario should mark the region as
> "RS_ZK_REGION_FAILED_ERROR" (or something to the effect) in the Zookeeper
> which should indicate the Master to stop assigning the region until the error
> has been resolved (via an HBase shell command, probably "assign"?)
