Alexey, Something is wrong, but I don't see any obvious mistakes in your code. Is it possible to provide a test as a standalone GitHub project so that I can run it and reproduce the problem?
Is it reproduced on smaller data sets? Or if load not through Spark, but just doing regular put/putAll operations or via IgniteDataStreamer? -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
