Taras Ledkov commented on IGNITE-4756:
--------------------------------------

[~javaller], my comments:
# You mustn't initialize {log} member at the {{RendezvousAffinityFunctionSimpleBenchmark#beforeTestsStarted}}.
It have been initialized early.
# Then Log4JLogger dependency is not needed. Please remove it from the {{core}} module.

> Summarize discussions:
> Add log message in case partitions distribution is not close to even distribution:
> # Add system property IGNITE_PART_DISTRIBUTION_WARN_THRESHOLD with default value 0.1
to print warn message only when nodes count differs more then threshold;
> # The statistic is calculated and printed only for the local node;
> # Message format is
> {noformat}
> Affinity assignment distribution not even [cache=<cache_name>, even=<golden_partitions_count>,
distribution=[<partitions_count_primary>, <partitions_count_backup0> ..., <partitions_count_backupN>]].
> e.g.:
> Affinity assignment distribution not even [cache=test, even=100 (10%), distribution=[100
(10%), 150 (15%), 500 (50%)]].
> {noformat}
