Configuring JasperReports Server with the Cassandra Connector
Deploy the connector
Download the Cassandra Connector. Unzip it. Copy the files in WEB-INF into your JasperReports Server instance. Be sure to keep the folder structure when copying the files. In connector version 0.5.1 these are the files:
WEB-INF/applicationContext-CassandraDataSource.xml WEB-INF/bundles/CassandraDataSource.properties WEB-INF/lib/cassandra-clientutil-1.0.9.jar WEB-INF/lib/cassandra-jdbc-1.0.5-SNAPSHOT.jar WEB-INF/lib/cassandra-thrift-1.0.9.jar WEB-INF/lib/guava-r08.jar WEB-INF/lib/js-cassandra-datasource-0.5.1.jar WEB-INF/lib/json-org-1.0.jar WEB-INF/lib/libthrift-0.6.1.jar ** The json-org-1.0.jar file was not in the zip file. I had to download it from the web to get things to work. **
Special fix: remove the Hive libraries which ship with JasperReports Server since these conflict with Cassandra (clashing Thrift versions). Here are the scripted changes for a Linux instance, but you can just delete (or rename) the files manually:
mv WEB-INF/lib/hive-common-0.8.1.jar WEB-INF/lib/hive-common-0.8.1.ja_ mv WEB-INF/lib/hive-exec-0.8.1.jar WEB-INF/lib/hive-exec-0.8.1.ja_ mv WEB-INF/lib/hive-jdbc-0.8.1.jar WEB-INF/lib/hive-jdbc-0.8.1.ja_ mv WEB-INF/lib/hive-metastore-0.8.1.jar WEB-INF/lib/hive-metastore-0.8.1.ja_ mv WEB-INF/lib/hive-service-0.8.1.jar WEB-INF/lib/hive-service-0.8.1.ja_
Restart JasperReports Server.
Define a connection
Right-click on a folder in the Repository View in JasperReports Server. Use the context menu to add a data source. The data source definion should follow the model shown below.
Use either the JasperReports Server web interface or iReport to deploy the report to JasperReports Server.
