Minor Description
In spark2.0, when run spark-sql and try to do select rand(null), it failed and the error message as follows:
> select rand(null);
INFO SparkSqlParser: Parsing command: select rand(null)
Error in query: Input argument to rand must be an integer literal.;; line 1 pos 7
In hive or mysql, I do the same operation(select rand(null)), it will success and the value of rand(null) is the same with rand(0).
this issue has fixed in Hive, the jira link as follows:
