------------------------------------------------------------
Upload a patch which adds a new interface, AsyncRegion. We pass a
RegionOperationContext with deadline (or other information in future) and get
the result or exception with it. This issue only adds this new interface and
handle TimeoutException at RPCServer. HRegion implements the methods of
AsyncRegion but now they are only wrapping blocking methods.
In future, we can use the deadline to prevent wasting time on blocking
operations in HRegion (other sub-tasks of HBASE-16492 will do this). And
finally we can make operations of AsyncRegion fully non-blocking and Region's
blocking methods will wrap non-blocking methods, or even we can remove the
interface of blocking methods.
[~Apache9] [~carp84] Any suggestions? Thanks.
