Subject [jira] [Created] (SPARK-25010) Rand/Randn should produce different values for each execution in streaming query
Date Thu, 02 Aug 2018 23:28:00 GMT
Liang-Chi Hsieh created SPARK-25010:
---------------------------------------

             Summary: Rand/Randn should produce different values for each execution in streaming
query
                 Key: SPARK-25010
                 URL: https://issues.apache.org/jira/browse/SPARK-25010
             Project: Spark
          Issue Type: Bug
          Components: SQL, Structured Streaming
    Affects Versions: 2.4.0
            Reporter: Liang-Chi Hsieh


Like Uuid in SPARK-24896, Rand and Randn expressions now produce the same results for each
execution in streaming query. It doesn't make too much sense for streaming queries. We should
make them produce different results as Uuid.
