RE: Mumak tutorial and how to build Mumak from source code

Hi all,
I think I'm using Hadoop 1.x: Das-MacBook-Air:hadoop-mapreduce dma$ ls 
src/contrib/mumak/
bin             build.xml       conf            ivy             ivy.xml         
src
And even I clone from "https://github.com/apache/hadoop-mapreduce";, I got the 
following error:


compile-mapred-classes:
    [javac] /Users/dma/hadoop-mapreduce/build.xml:351: warning:

So can any one help one those error? BTW, Mumak is the requirement for the 
project, can not be changed.
Java version: 1.8Ant version: 1.9.4
If any comments, please let me know.
