Subject [jira] [Commented] (SPARK-1945) Add full Java examples in MLlib docs
Date Wed, 09 Jul 2014 12:06:05 GMT


Michael Yannakopoulos commented on SPARK-1945:

Thanks Xiangrui,

I have already figured it out. Today, I am going to update my patches so as to comply to the
coding standards.
Thanks for you help and for pointing out to me all the aforementioned issues.

>                 Key: SPARK-1945
>                 URL:
>             Project: Spark
>          Issue Type: Sub-task
>          Components: Documentation, MLlib
>            Reporter: Matei Zaharia
>              Labels: Starter
>             Fix For: 1.0.0
> Right now some of the Java tabs only say the following:
> "All of MLlib’s methods use Java-friendly types, so you can import and call them there
the same way you do in Scala. The only caveat is that the methods take Scala RDD objects,
while the Spark Java API uses a separate JavaRDD class. You can convert a Java RDD to a Scala
one by calling .rdd() on your JavaRDD object."
> Would be nice to translate the Scala code into Java instead.
> Also, a few pages (most notably the Matrix one) don't have Java examples at all.
