             Summary: SQL fails to parse when comment contains an unmatched quote character
                 Key: SPARK-30049
                 URL: https://issues.apache.org/jira/browse/SPARK-30049
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Jason Darrell Lowe


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}
