Subject Java: Return type of RDDFunctions.sliding(int, int)
Date Fri, 13 May 2016 07:40:53 GMT
Hello,

We're trying to use PrefixSpan on sequential data, by passing a sliding
window over it. Spark Streaming is not an option.
RDDFunctions.sliding() returns an item of class RDD<Java.lang.Object>,
regardless of the original type of the RDD. Because of this, the
returned item seems to be pretty much worthless.
Is this a bug/nyi? Is there a way to circumvent this somehow?

Official docs:
https://spark.apache.org/docs/1.6.0/api/java/org/apache/spark/mllib/rdd/RDDFunctions.html

Thanks
