在 Kafka 连接器中获取 Ignite 异常

Question

I am running 3 servers and 1 client topology.

1 of the servers node is being run by kafka connector process.

client is not able to send any message to that kafka connector ignite node.

this is the exception

Answer 1

Direct type -33 is GridH2QueryRequest .

Are you sure that your Kafka connector node has ignite-indexing in its classpath? Try adding it explicitly.
