[jira] [Created] (DRILL-4486) Expression serializer incorrectly serializes escaped characters

Steven Phillips created DRILL-4486:
--------------------------------------

             Summary: Expression serializer incorrectly serializes escaped characters
                 Key: DRILL-4486
                 URL: https://issues.apache.org/jira/browse/DRILL-4486
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Steven Phillips
            Assignee: Steven Phillips


the drill expression parser requires backslashes to be escaped. But the ExpressionStringBuilder is not properly escaping them. This causes problems, especially in the case of regex expressions run with parallel execution.
