Can not integrate ignite with cassandra

Question

I can not integrate cassandra with ignite. I tried many methods but none of them worked.

I added the optional libraries to lib folder. But no result. When I tried the example1 provided in the ignite document, Then I got the classpath error.

I am using ignite version 2.6 and cassandra version 3.11.4

This is my config file

This is not a classpath error. Spring reports, that there is no bean called cassandraDataSource. Judging by the comment in your configuration file  and no bean definitions under it, looks like you removed the corresponding configuration part.

So, you need to configure the data source for Cassandra. You can refer to the documentation for more details: https://apacheignite-mix.readme.io/docs/ignite-with-apache-cassandra

Configuration examples: https://apacheignite-mix.readme.io/docs/examples

Hi I edited the file . But I got the FileNotFound Exception.How to solve this issue. I am using Ignite first time – Ashok v Jul 06 '19 at 15:26
It means that you specified an import directive, but you don't have a corresponding file on the classpath. It's supposed to be a data source bean there. Take a look at the contents of `connection-settings.xml ` on the examples page: https://apacheignite-mix.readme.io/docs/examples – Denis Jul 08 '19 at 17:38
I solved it by specifying correct path, Now this is my new issue https://stackoverflow.com/questions/56933378/failed-to-execute-cassandra-cql-statement-while-reading-from-ignite-cache?noredirect=1#comment100416384_56933378 – Ashok v Jul 09 '19 at 03:42
