-------------------------------------
Summary: Fix broken current folder expansion during MR job start
Key: MAPREDUCE-7225
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7225
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 3.0.3, 2.9.0
Reporter: Adam Antal
Assignee: Adam Antal
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
