      Description

      Starting a sleep job giving "." as files that should be localized is working fine up until 2.9.0, but after that the user is given an IllegalArgumentException. This change is a side-effect of HADOOP-12747 where GenericOptionsParser#validateFiles function got modified.

      Can be reproduced by starting a sleep job with "-files ." given as extra parameter. Log:

      sudo -u hdfs hadoop jar hadoop-mapreduce-client-jobclient-3.0.0.jar sleep -files . -m 1 -r 1 -rt 2000 -mt 2000
