Anton Dmitriev updated IGNITE-9055:
-----------------------------------
Description:
Method calculateUpdates throws NPE in case of empty partitions. Reduce function
user in this method doesn't handle correctly empty arguments ((a, b) -> a ==
null ? b : a.plus(b))).
We need to fix this reduce function or update Partition Based Dataset so that
it doesn't emit empty arguments.

function user in this method doesn't handle correctly empty arguments (`(a, b)
-> a == null ? b : a.plus(b))`).
