             Summary: Ignite start hangs infinitely when sync preloading is cancelled
                 Key: IGNITE-9404
                 URL: https://issues.apache.org/jira/browse/IGNITE-9404
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.6
            Reporter: Ivan Pavlukhin


This case fires very rarely in {{TcpDiscoveryRestartTest.testRestart}}. Caches with {{SYNC}} rebalance mode are affected. When **starting** instance is trying to preload partitions for such cache from another instance which **stops** around the same time, first instance could hang infinitely. When {{SYNC}} rebalance mode is enabled starting instance awaits on **preload future** in start routine. In another thread it starts fetching partitions and receives an error from **stopping** instance and cancels **rebalance future** but **preload future** is not cancelled.
