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.
