      Description

      If the number of Map task is more than 200 and using dynamic option, DistCp always fails by DynamicInputFormat#validateNumChunksUsing. This failure is after building the src/dst paths, which takes more than 10 minutes if the directory is large (i.e. DistCp fails by configuration error after more than 10 minutes).

      I think DistCp should validate the configuration before building the src/dst paths and fail if the configuration is not valid.
