-----------------------------------------------------------
distcp uses parameters
* from distcp-default.xml, which overrides
hdfs-site.xml,yarn-site.xml,mapred-site.xml
* from -D in commandline.
I think we should add another way to set parameters to override
distcp-default.xml. If distcp runs with -D every time, it is boring. it is
useful for adding distcp-site.xml
