Brock Noland created HIVE-5350:
----------------------------------
Summary: Cleanup exception handling around parallel orderby
Key: HIVE-5350
URL: https://issues.apache.org/jira/browse/HIVE-5350
Project: Hive
Issue Type: Bug
Reporter: Brock Noland
Priority: Minor
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}
