Hadoop-Hive Reports Not Running

If you created a Hadoop-Hive data source in JasperReports Server 5.6 or earlier, it may not run when imported to a more recent version of the server, for example after an upgrade. The reason is the changes to the Hadoop-Hive connectors.

To update Hadoop-Hive data sources:

1. Create a new Hive data source using the same URL as the old Hadoop-Hive data source used by your reports. If you're using Cloudera 5, create a CDH 5 Hive-Impala data source. For all other hive servers, create a JDBC data source that uses the Hive JDBC driver. For instructions, see Hadoop-Hive Data Sources.
2. Update your Hadoop-Hive-based reports to use the new data source.
3. Delete the old, imported data source.
