Description

The mapred command on Windows does not set HADOOP_OPTS correctly. As a result, some options and settings will miss in the final command, and this will lead to some desired behavior missing. One example is the logging file setting will miss, i.e. even if one set HADOOP_ROOT_LOGGER to DRFA, there is no history server log at HADOOP_LOGFILE.
