> I think we should log the message to the console and the full exception to
> the log:
> ExecDriver:
> {noformat}
> try {
> handleSampling(driverContext, mWork, job, conf);
> job.setPartitionerClass(HiveTotalOrderPartitioner.class);
> } catch (Exception e) {
> console.printInfo("Not enough sampling data.. Rolling back to
> single reducer task");
> rWork.setNumReduceTasks(1);
> job.setNumReduceTasks(1);
> }
> {noformat}
