Assignee: Reza Zadeh
> Iterators in columnSimilarities to allow flatMap spill
> ------------------------------------------------------
>
> Key: SPARK-6713
> URL: https://issues.apache.org/jira/browse/SPARK-6713
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Reporter: Reza Zadeh
> Assignee: Reza Zadeh
> Fix For: 1.4.0
>
>
> We should use Iterators in columnSimilarities to allow mapPartitionsWithIndex
> to spill to disk. This could happen in a dense and large column - this way
> Spark can spill the pairs onto disk instead of building all the pairs before
> handing them to Spark.
