> time between deciding the source and destination path for distcp to invoking 
> of distcp can have a change of the source file, hence distcp might copy the 
> wrong file to destination, hence we should an additional check on the 
> checksum of the source file path after distcp finishes to make sure the path 
> didnot change during the copy process. if it has take additional steps to 
> delete the previous file on destination and copy the new source and repeat 
> the same process as above till we copy the correct file.
