Cannot use OLAP schema with a Hadoop Hive data source

Hello!

Even though I am using an OLAP schema file similar to the one that works for a JDBC data source (towards Oracle DB), this schema file is not recognized when using a Hadoop Hive datasource (which I successfully used to run static reports, by the way). When, in Jasper Reports Server, I try to use the cube definitions from the defined OLAP schema file inorder to create Ad Hoc reports (by clicking Create -> Ad Hoc Report -> OLAP Connections), I cannot see and choose the cubes under the Mondrian connection which I defined. As you may know, when the cubes do not appear there, this is a sign of error from Jasper.

The following error message appears in the Apache Tomcat log:

WARN OlapConnectionTreeProvider,http-8080-7:106 - Can not load information about OLAP cubes from OLAP connection: SHE_Connection_HADOOP

java.lang.ClassCastException: com.jaspersoft.jasperserver.api.metadata.jasperreports.domain.client.CustomReportDataSourceImpl cannot be cast to com.jaspersoft.jasperserver.api.metadata.jasperreports.domain.JndiJdbcReportDataSource
