--------------------------------------------

Hi [~Yibing],
do you have the free time to do the refactoring suggested by Peter? If not then I'd be happy to add the final touch. The patch looks good, so it would be a shame to not commit it.

> By default, {{MapredLocalTask}} is executed in a child process of Hive, in case the local task uses too much resources that may affect Hive. Currently, the stdout and stderr information of the child process is printed in Hive's stdout/stderr log, which doesn't have a timestamp information, and is separated from Hive service logs. This makes it hard to troubleshoot problems in MapredLocalTasks.
