Failed to execute Cassandra CQL statement, while reading from Ignite Cache - apache-spark

Question

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.

Caused by: java.lang.NoSuchMethodError: com.google.common.util.concurrent.Futures.withFallback(Lcom/google/common/util/concurrent/ListenableFuture;Lcom/google/common/util/concurrent/FutureFallback;Ljava/util/concurrent/Executor;)Lcom/google/common/util/concurrent/ListenableFuture;
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?

Answer 2

I solved this issue by changing the Guava version. I added guava 19.0 to $IGNITE_HOME/libs/ folder.
