----------------------------------------
Summary: Indexing for vectors in MLlib
Key: SPARK-2909
URL: https://issues.apache.org/jira/browse/SPARK-2909
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Joseph K. Bradley
Priority: Minor
Vectors (DenseVector and SparseVector) 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.
