R=C3=A9my SAISSY commented on YARN-126:
----------------------------------

I removed the GenericOptionsParser because I saw that the yarn distributed =
shell ApplicationMaster.java relies on org.apache.commons.cli.GnuParser ins=
tead.
So I though that since an options parser is not something specific to Hadoo=
p, it might be a good thing to remove the GenericOptionParser dependency wh=
ere it is possible to favor the commons.cli library instead.
Isn't it the case?
