----------------------------------------------------------------
In this case I suggest to extend public API in one of the following ways:
- make cache(CACHE_NAME).rebalance().get() return boolean,
- add another future that will automatically retry rebalance until it is
successful.
Currently cache(CACHE_NAME).rebalance() looks useless, and user doesn't have
any ability to enforce rebalancing.

> Dynamic cache with rebalanceDelay == -1 doesn't trigger late affinity
> assignment even after explicit rebalance is called on every node

> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.4
> Reporter: Ilya Lantukh
> Assignee: Maxim Muzafarov
> Priority: Major
> Fix For: 2.6
>
>
> Reproducer:
> {noformat}
> startGrids(NODE_COUNT);
> IgniteEx ig = grid(0);
> ig.cluster().active(true);
> awaitPartitionMapExchange();
> IgniteCache<Integer, Integer> cache =
> ig.createCache(
> new CacheConfiguration<Integer, Integer>()
> .setName(CACHE_NAME)
> .setCacheMode(PARTITIONED)
> .setBackups(1)
> .setPartitionLossPolicy(READ_ONLY_SAFE)
> .setReadFromBackup(true)
> .setWriteSynchronizationMode(FULL_SYNC)
> .setRebalanceDelay(-1)
> );
> for (int i = 0; i < NODE_COUNT; i++)
> grid(i).cache(CACHE_NAME).rebalance().get();
> awaitPartitionMapExchange();
> {noformat}
> Sometimes this code will hang on the last awaitPartitionMapExchange(), though
> probability that it will happen is rather low (<10%).
