Deron Eriksson commented on SYSTEMML-138:
-----------------------------------------

Note: Currently MR1 is still supported, so deprecated classes/methods should not be changed if this breaks MR1 compatibility.

> A number of deprecated Hadoop classes and methods are currently utilized by SystemML. Right now deprecation warnings are being suppressed by utilizing @SuppressWarnings("deprecation") annotations.
> References to deprecated classes and methods should be updated to non-deprecated classes and methods.
> Examples include:
> Path.makeQualified(FileSystem fs)
> SequenceFile.Reader.Reader(FileSystem fs, Path file, Configuration conf)
> SequenceFile.Writer.Writer(FileSystem fs, Configuration conf, Path name, Class keyClass, Class valClass)
> DistributedCache.addCacheFile(URI uri, Configuration conf)
> DistributedCache.createSymlink(Configuration conf)
