If you created a Hadoop-Hive data source in some older JasperReports Server versions before Version 6, it may not run when imported to a more recent version of the server. This problem is caused by 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.|
