Nick Dimiduk commented on HBASE-12012:
--------------------------------------
No test changes?
I like the Cancellable interface too.
Separate interface? Can we not push this feature down into all
{{RetryingCallables}}?
{noformat}
[email protected]
+interface CancellableCallable<T> extends RetryingCallable<T> {
+ public void startCancel();
+}
{noformat}
Down in ScannerCallableWithReplicas, should the change to {{canceled}} and call
to {{caller.cancel()}} be synchronized?
{noformat}
+ @Override
+ public void startCancel() {
+ canceled = true;
+ caller.cancel();
+ if (callable.getController() != null) {
+ callable.getController().startCancel();
+ }
{noformat}
> Improve cancellation for the scan RPCs
