Lars Hofhansl commented on HBASE-9740:
--------------------------------------
Assigned to Ping. Looking at the patch, the map logic can probably be expressed
a lot nicer with a ConcurrentMap (putIfAbsent, etc).
> A corrupt HFile could cause endless attempts to assign the region without a
> chance of success

> 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"?)
