Lars Hofhansl resolved HBASE-6522.
----------------------------------
Resolution: Fixed
Fix Version/s: 0.94.2
0.96.0
Hadoop Flags: Reviewed
At the same time we can tackle this in another jira when it turns out to
actually be a problem. As it stands in 0.94 all leases take default leasePeriod
configured for this region server.

> 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)
