Alicia Ying Shu commented on HBASE-12787:
-----------------------------------------
public interface RpcSchedulerFactory {
/**
* Constructs a {@link org.apache.hadoop.hbase.ipc.RpcScheduler}.
*
* Please note that this method is called in constructor of {@link
HRegionServer}, so some
* fields may not be ready for access. The reason that {@code HRegionServer}
is passed as
* parameter here is that an RPC scheduler may need to access data structure
inside
* {@code HRegionServer} (see example in {@link SimpleRpcSchedulerFactory}).
*/
RpcScheduler create(Configuration conf, RegionServerServices server);
}
RegionServerServices already extends Abortable. There is no interface change in
0.98 for this feature.

> Backport HBASE-12028 (Abort the RegionServer when it's handler threads die)
> to 0.98. There are two 0.98-specific changes that should be addressed:
> # The default configuration should preserve current behavior
> # The interface change to RpcSchedulerFactory should be binary compatible for
> Phoenix if possible, and we can do this by detecting with reflection if an
> older implementation of the interface is missing the new 'create' method and
> by invoking the older deprecated 'create' method instead. We can cache the
> decision after making it once.
