Joseph K. Bradley updated SPARK-2909:
-------------------------------------
Component/s: PySpark
> Indexing for vectors in pyspark
> -------------------------------
>
> Key: SPARK-2909
> URL: https://issues.apache.org/jira/browse/SPARK-2909
> Project: Spark
> Issue Type: Improvement
> Components: MLlib, PySpark
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> Vectors (DenseVector and SparseVector) in pyspark do not currently support
> indexing, except by examining the internal representation. Though indexing
> is a pricy operation, it would be useful for, e.g., iterating through a
> dataset (RDD[LabeledPoint]) and operating on a single feature.
