I have to generate Jasper Report using JasperSoft Studo using data from Cassandra.
I created connection between JasperSoft Studio 6.2.2 and Apache Cassandra 3.5 successfully, but I am getting following error while retrieving data from Cassandra.
(CassandraDataAdapterService.java:40) contributeParameters(..) : hostname: 127.0.0.1
