             Summary: Potential further bugs with DurableBackgroundTasks.
                 Key: IGNITE-13565
                 URL: https://issues.apache.org/jira/browse/IGNITE-13565
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 2.8.1
            Reporter: Stanilovsky Evgeny


After some code refactoring [1] we obtain a problem with simpe test: org.apache.ignite.internal.processors.cache.index.BasicIndexTest#testInlineSizeChange
between 

{noformat}
execSql(cache, "drop index \"idx1\"");
{noformat}
and

{noformat}
ig0 = startGrid(0);
{noformat}

operations, seems [2] will fix it but problem could potentially happen again (check attached stacks). In few words already completed durable task not updated 

{noformat}
DurableBackgroundTask#complete
{noformat}
status on metastore, thus after cluster running this task still can try t run once more with undefined behavior. [~Denis Chudov] [~makedonskaya] pay your attention plz.
