Dmitry Lazurkin updated IGNITE-14524:
-------------------------------------
Description:
I have big cache with configured rebalanceMode = ASYNC, rebalanceDelay =
10_000ms. Persistence is enabled, maxWalArchiveSize = 10GB. And I passed
-DIGNITE_PREFER_WAL_REBALANCE=true and -DIGNITE_PDS_WAL_REBALANCE_THRESHOLD=1
to Ignite. So node should use historical rebalance if there is enough WAL. But
it doesn't. After investigation I found that
GridDhtPreloader#generateAssignments always get called with exchFut = null, and
this method can't set histPartitions without exchFut. I think, that problem in
GridCachePartitionExchangeManager
(https://github.com/apache/ignite/blob/bc24f6baf3e9b4f98cf98cc5df67fb5deb5ceb6c/modules/core/src/main/java/org/apache/ignite/internal/processors/cache/GridCachePartitionExchangeManager.java#L3486).
It doesn't call generateAssignments without forcePreload if rebalanceDelay is
configured.
Historical rebalance works after removing rebalanceDelay.
