> A SQL statement that contains a comment with an unmatched quote character can lead to a parse error.  These queries parsed correctly in older versions of Spark.  For example, here's an excerpt from an interactive spark-sql session on a recent Spark-3.0.0-SNAPSHOT build (commit e23c135e568d4401a5659bc1b5ae8fc8bf147693):
> {noformat}
> spark-sql> SELECT 1 -- someone's comment here
>          > ;
> Error in query: 
> extraneous input ';' expecting <EOF>(line 2, pos 0)
> == SQL ==
> SELECT 1 -- someone's comment here
> ;
> ^^^
> {noformat}
