问题
I am trying to integrate ignite with cassandra. I set up the configuration and started the ignite node. But I can not insert/read data from Ignite cache/cassandra db. I created Keyspace and table in the cassandra. And inserted some values. But when tried to read the values , the exception arises. Same thing happened when I tried to insert some values.
My Ignite version is 2.6 and cqlsh 5.0.1 | Cassandra 3.11.4 | CQL spec 3.4.4 | spark version is 2.3.0 | scala version is 2.11.8 | cassandra driver core 3.0.0 | guava 19.0 |
This is ignite configuration.

To start spark-shell Am using the following command
bin/spark-shell --conf "sparkor.extraClassPath=/etc/ignite/libs/*:/etc/ignite/libs/optional/ignite-spark/*:/etc/ignite/libs/optional/ignite-log4j/*:/etc/ignite/libs/optional/ignite-yarn/*:/etc/ignite/libs/ignite-spring/*:/etc/ignite/libs/ignite-cassandra-store/*"

This looks like you've got a JAR hell, i.e., your Cassandra version is not compatible with your google common util version. What build/dependency system are you using?
