Aleksey Plekhanov created IGNITE-8166:
-----------------------------------------

             Summary: stopGrid() hangs in some cases when node is invalidated and PDS is enabled
                 Key: IGNITE-8166
                 URL: https://issues.apache.org/jira/browse/IGNITE-8166
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.5
            Reporter: Aleksey Plekhanov


Node invalidation via FailureProcessor can hang {{exchange-worker}} and {{stopGrid()}} when PDS is enabled.

Reproducer (reproducer is racy, sometimes finished without hang):
{code:java}
public class StopNodeHangsTest extends GridCommonAbstractTest {
    /** Offheap size for memory policy. */
    private static final int SIZE = 10 * 1024 * 1024;

    /** Page size. */
    static final int PAGE_SIZE = 2048;

    /** Number of entries. */
    static final int ENTRIES = 2_000;

    /** {@inheritDoc} */
    @Override protected IgniteConfiguration getConfiguration(String igniteInstanceName) throws Exception {
        IgniteConfiguration cfg = super.getConfiguration(igniteInstanceName);

        DataStorageConfiguration dsCfg = new DataStorageConfiguration();

        DataRegionConfiguration dfltPlcCfg = new DataRegionConfiguration();

        dfltPlcCfg.setName("dfltPlc");
        dfltPlcCfg.setInitialSize(SIZE);
        dfltPlcCfg.setMaxSize(SIZE);
        dfltPlcCfg.setPersistenceEnabled(true);

        dsCfg.setDefaultDataRegionConfiguration(dfltPlcCfg);
        dsCfg.setPageSize(PAGE_SIZE);

        cfg.setDataStorageConfiguration(dsCfg);

        cfg.setFailureHandler(new FailureHandler() {
            @Override public boolean onFailure(Ignite ignite, FailureContext failureCtx) {
                return true;
            }
        });

        return cfg;
    }

    public void testStopNodeHangs() throws Exception {
        cleanPersistenceDir();

        IgniteEx ignite0 = startGrid(0);
        IgniteEx ignite1 = startGrid(1);

        ignite1.cluster().active(true);

        awaitPartitionMapExchange();

        IgniteCache cache = ignite1.getOrCreateCache("TEST");

        Map<Integer, Object> entries = new HashMap<>();

        for (int i = 0; i < ENTRIES; i++)
            entries.put(i, new byte[PAGE_SIZE * 2 / 3]);

        cache.putAll(entries);

        ignite1.context().failure().process(new FailureContext(FailureType.CRITICAL_ERROR, null));

        stopGrid(0);
        stopGrid(1);
    }
}
{code}

{{stopGrid(1)}} waiting until exchange finished, {{exchange-worker}} waits on method {{GridCacheDatabaseSharedManager#checkpointReadLock}} for {{CheckpointProgressSnapshot#cpBeginFut}}, but this future is never done because {{db-checkpoint-thread}} got exception at {{GridCacheDatabaseSharedManager.Checkpointer#markCheckpointBegin}} thrown by {{FileWriteAheadLogManager#checkNode}} and leave method {{markCheckpointBegin}} before future is done ({{curr.cpBeginFut.onDone();}})
