```
all warnings of `$HADOOP` stuff is my personal setup for Rhipe.  


Currently, there are two open issues on the last two things to fix.  

```
'require' calls not declared from:
  'data.table' 'digest'
```

and

```
no visible binding for '<<-' assignment
```

Yay

p.s. good luck on installing for travis

## on mac...
brew install maven
brew install protobuf241
brew install ant

g clone https://github.com/amplab-extras/SparkR-pkg.git
cd  SparkR-pkg/
USE_MAVEN=1 ./install-dev.sh # typical install with ant failed for me. :-(

download and open http://ml.stat.purdue.edu/rhipebin/Rhipe_0.73.1-4.tar.gz
