Parallelize on Hadoop
Good news:
– Mahout, a parallel machine learning tool, is
already available.
– There are Mallet, libsvm, Weka, … that support
necessary algorithms.
Bad news:
– Mahout doesn’t support necessary algorithms
yet.
– Other algorithms do not run natively on Hadoop.
build a flexible ML platform running on
Hadoop
Pig for Hadoop implementation.
