Changes in 7.1 That May Affect Your Upgrade

Changes to the Login Page

The layout of the login page changed in JasperReports Server 7.1. There were no changes to the CSS classes, but some default values were changed. If you have customized the login page, you should make sure your customizations still have the desired effect in 7.1, and make any necessary changes.

If you have not customized the Login page, this change will not affect you.

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 Cloud Software Group 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.
