-----------------------------------

             Summary: Parse Boolean type in JDBC driver
                 Key: KYLIN-2824
                 URL: https://issues.apache.org/jira/browse/KYLIN-2824
             Project: Kylin
          Issue Type: Bug
          Components: Driver - JDBC
            Reporter: Tianhao Zhao
            Priority: Minor


Exception below is thrown when querying kylin with Saiku as front end, or when retrieving value from getBoolean method in jdbc driver.
That's because KylinClient in jdbc module dose not parse value properly when dimension is boolean type.

Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean
