-----------------------------------
Summary: Simpler Dataset.sample API
Key: SPARK-21777
URL: https://issues.apache.org/jira/browse/SPARK-21777
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 2.2.0
Reporter: Reynold Xin
Assignee: Reynold Xin
Dataset.sample requires a boolean flag withReplacement as the first argument.
However, most of the time users simply want to sample some records without
replacement. This ticket introduces a new sample function that simply takes in
the fraction and seed.
