Lars Hofhansl updated HBASE-6522:
---------------------------------
Attachment: 6522-v2.txt
V2 also fixes up the mock implementations of RSServices and add some simple
test code
(which just makes sure that getLeases() and getLock(...) is accessible and can
be called from a RegionObserver implementation).
> Expose locks and leases to Coprocessors
> ---------------------------------------

>
> 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)
