> This issue can be reproduced by the following snippet:
> {code}
> spark.range(1).createOrReplaceTempView("test")
> spark.sql("SELECT MAX(COUNT(*)) FROM test GROUP BY id")
> {code}
> An analysis phase error report like the following is expected:
> bq. It is not allowed to use an aggregate function in the argument of another aggregate function. ...
> However, this error is not captured at analysis phase, but leads an execution time exception:
> bq. Error in SQL statement: SparkException: Job aborted due to stage failure: Task 9 in stage 355.0 failed 4 times, most recent failure: Lost task 9.3 in stage 355.0 (TID 12920, ip-10-31-224-146.ec2.internal): java.lang.UnsupportedOperationException: Cannot evaluate expression: (count(1),mode=Complete,isDistinct=false)
