Re: Simple connect to gridgain via java for taken data

Hi, Are you sure to use same Ignite version on server and client, where are you using Ignite JDBC connection? The message: *Remote node has cache affinity assignment mode different from local* look like you apply different configuration on client and on server. Also, you can access to date using

Re: Reassign partitions

AffinityFunction has to return the same result for the same topology anyway, this is the crucial contract. Having said that, I still don't understand how calling it at a random moment of time will help. Do you have a test project that you can share with us? This would make things more clear.
