> Scan query map nodes do not take into account topology version when filtering primary partitions. See method {{GridCacheQueryManager#scanIterator}} - each node takes it's current topology version. This causes wrong partition filtering results.
> To fix this problem the single topology version should be taken on reduce node propagated to map nodes.
