Changes in 6.4 That May Affect Your Upgrade

Removal of the Impala Connector

JasperReports Server provides new and updated drivers for various databases. In the 6.2 release, the previous connector for Impala that had been available on the Jaspersoft community website was replaced with the Simba JDBC driver (Cloudera-endorsed JDBC interface).

By default, the new release supports the new JDBC driver, and the old Impala connector cannot be used. You should update your Impala data sources to use the new driver. For more information, see the JasperReports Server Community Project Administrator Guide.

If you wish to continue using the Impala connector that was previously available from the community website, modify the install as described below.

1. Add the following files to the <js-install>/WEB-INF/lib directory:
     hive-service-0.12.0-cdh5.1.3.jar
     zookeeper-3.4.5-cdh5.1.3.jar
     avro-1.7.5-cdh5.1.3.jar
     commons-compress-1.4.1.jar
     hadoop-core-1.2.1.jar
     hive-ant-0.12.0-cdh5.1.3.jar
     hive-common-0.12.0-cdh5.1.3.jar
     hive-exec-0.12.0-cdh5.1.3.jar
     hive-jdbc-0.12.0-cdh5.1.3.jar
     jasperserver-hive-connector-bugfix-SNAPSHOT.jar
     js-hive-datasource-1.2.1-cdh5.jar
     paranamer-2.3.jar
     parquet-hadoop-bundle-1.2.5-cdh5.1.3.jar
     xz-1.0.jar
2. Delete the file applicationContext-HiveDatasource.xml from the <js-install>/WEB-INF directory:

If you do not add the files listed, data sources that use the old Impala connector will cause errors when running reports that rely on them.
