Hi everyone!
I'd like to take a stab at fixing it.

> When I try to delete a row from a not existing table, the error is quite confusing. Instead of getting a table not found exception I got 
> {noformat}
> ERROR [main] client.AsyncRequestFutureImpl: Cannot get replica 0 location for {"totalColumns":1,"row":"r1","families":{"c1":[{"qualifier":"","vlen":0,"tag":[],"timestamp":9223372036854775807}]},"ts":9223372036854775807}
> ERROR: Failed 1 action: t1: 1 time, servers with issues: null
> {noformat}
> That happens, because delete is using AsyncRequestFuture which wraps all region location errors into 'Cannot get replica' error.  I expect that others actions like batch, mutateRow, checkAndDelete behave in the same way.
