Lars Hofhansl commented on HBASE-6522:
--------------------------------------
@Stack: Yep, because that is all a RegionObserver can see (through the
RegionCoprocessorEnvironment). I think it also makes sense, because it is a
service provided by the RegionServer.

> Currently it is not possible for CP to implement any of checkAndMutate type
> operations, because coprocessor have no way create a lock, because getLock is
> private HRegion (interestingly ReleaseLock is public).
> In addition it would nice if Coprocessor could hook into the RegionServers'
> Lease management.
> Here I propose two trivial changes:
> # Make HRegion.getLock public
> # Add {code}Leases getLeases(){code} to RegionServerServices (and hence to
> HRegionServer)
