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