title: How to do text analysis in Spark
body: <p>I'm quite familiar with Hadoop but totally new to Apache Spark. Currently I'm using LDA (Latent Dirichlet Allocation) algorithm implemented in Mahout to do topic discovery. However as I need to make the process faster I'd like to use spark, however the LDA (or CVB) algorithm is not implemented in Spark MLib. Does this mean that I have to implement it from scratch by myself? If so, does Spark provide some tools that make it easier?</p>
