Description

When we used wrong command line arg for specify log file pattern, yarn did not throw any exception instead it pulled entire log onto the client.

[hive@ctr-e20-1468887904486-0007-01-000003 ~]$ yarn logs -applicationId application_1470931023753_0001 -logFiles hive.*2016-08-11-21.* > logs

NOTE: we are using -logFiles instead of -log_files

This query should have failed.
