Apache Spark reassigned SPARK-15197:
------------------------------------
Assignee: Apache Spark
> Improve documentation for countApprox and related functions
> -----------------------------------------------------------
>
> Key: SPARK-15197
> URL: https://issues.apache.org/jira/browse/SPARK-15197
> Project: Spark
> Issue Type: Documentation
> Reporter: Nicholas Tietz

>
> Within RDD, JavaRDDLike, PairRDDFunctions, and JavaPairRDD, countApprox and countByValueApprox are missing Scaladoc on their input parameters and return values; in particular, it is unclear what unit the timeout is in and what the meaning of the confidence value is.
> We should document these parameters clearly. This includes:
> * documenting the timeout
> * documenting/clarifying the confidence meaning/constraints
> * adding a check in the code to ensure confidence is in the required range
> * clarifying documentation in related methods (such as more detail on relativeSD in similar approx methods).
