             Fix For: 1.2.3


For Mr or tez application, if the jar resources already exists on the HDFS, the application
will still upload the jars to the HDFS when it starts.I thind this is not need.
So, if the original resource file is already on HDFS,I will record it ,and when the application
starts, it will use the original file on HDFS.
