question: private String constructResultFileName ( ) { String scratchSpaceLoc = ConfigurationManager . getScratchSpace ( ) ; StringBuilder sb = new StringBuilder ( ) ; sb . append ( scratchSpaceLoc ) ; sb . append ( Lop . FILE_SEPARATOR ) ; sb . append ( Lop . PROCESS_PREFIX ) ; sb . append ( DMLScript . getUUID ( ) ) ; sb . append ( PARFOR_MR_RESULT_TMP_FNAME . replaceAll ( "%ID%" , String . valueOf ( _ID ) ) ) ; return sb . toString ( ) ; }
target:  NOTE: Only required for remote parfor. Hence, there is no need to transfer DMLConfig to the remote workers (MR job) since nested remote parfor is not supported.
