> DataFrame.describe() should cast all aggregates to String
> ---------------------------------------------------------
>
> Key: SPARK-7687
> URL: https://issues.apache.org/jira/browse/SPARK-7687
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.1
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Priority: Critical
>
> In DataFrame.describe(), the count aggregate produces an integer, the avg and
> stdev aggregates produce doubles, and min and max aggregates can produce
> varying types depending on what type of column they're applied to. As a
> result, we should cast all aggregate results to String so that describe()'s
> output types can match its declared output schema.
