Duo Zhang commented on HBASE-16505:
-----------------------------------

We'd better declare the error in RegionOperationContext as Throwable instead of 
Exception. It is more generic.

The patch itself is OK, does not break anything. But what's next? Especially 
for coprocessor. Do we need to change the coprocessor interface?

Thanks.

> Add AsyncRegion interface to pass deadline and support async operations
