> When creating a view, a common user error is the number of columns produced by the SELECT clause does not match the number of column names specified by CREATE VIEW.
> For example, given Table {{t1}} only has 3 columns
> {noformat}
> create view v1(col2, col4, col3, col5) as select * from t1
> {noformat}
> Currently, Spark SQL reports the following error:
> {noformat}
> requirement failed
> java.lang.IllegalArgumentException: requirement failed
> 	at scala.Predef$.require(Predef.scala:212)
> 	at org.apache.spark.sql.execution.command.CreateViewCommand.run(views.scala:90)
> {noformat}
> This error is very confusing.
