Hi,
> 1) What ports should be opened on driver machine or yarn machine?(There > issues were happned on our production env) Ignite by default using the following ports:11211 - REST, 47100..47200 - TCP communication, 47500...47600 - Discovery, 49112 - JMX. You can change the values (see TcpCommunicationSpi#setLocalPort and TcpDiscoverySpi#setLocalPort). About other issue, could you clarify your test environment and which configuration spark you using and which get correct/incorrect results? Standalone or embedded? YARN ignite cluster or local cluster?
