Description

I intend to dig into 'mapreduce.jobhistory.intermediate-done-dir' argument, the position of which is at `JHAdminConfig:73`, to get some comprehension on history server. This argument is referenced at `JobHistoryEventHandler.moveToDoneNow()`, where history server moves job summary file from "${yarn.app.mapreduce.am.staging-dir}/${user}/.staging" to "${mapreduce.jobhistory.intermediate-done-dir}/${user}".

Since the following code snippet in `moveToDoneNow()` will definitely write some logs out to log file, but I can found no any sign of it in all logs in $HADOOP_LOG_DIR via command `grep "Copied to done location" *`.
if (copied)
LOG.info("Copied to done location: " + toPath);
else
LOG.info("copy failed");

Is there anything that I missed?
