Kousuke Saruta created HIVE-13434:
-------------------------------------

             Summary: BaseSemanticAnalyzer.unescapeSQLString doesn't unescape \0000 style character literals.
                 Key: HIVE-13434
                 URL: https://issues.apache.org/jira/browse/HIVE-13434
             Project: Hive
          Issue Type: Bug
          Components: Parser
    Affects Versions: 2.1.0
            Reporter: Kousuke Saruta
            Assignee: Kousuke Saruta


BaseSemanticAnalyzer.unescapeSQLString method may have a fault. When "\u0061" style character literals are passed to the method, it's not unescaped successfully.

In Spark SQL project, we referenced the unescaping logic and noticed this issue (SPARK-14426)
