---------------------------------------

             Summary: Semaphore gets broken when one of nodes finishes normally and leaves topology
                 Key: IGNITE-4209
                 URL: https://issues.apache.org/jira/browse/IGNITE-4209
             Project: Ignite
          Issue Type: Bug
            Reporter: Sergey Chugunov


h4. Notes
Bug is reproducible with latest version of code available in master branch.

As [~vladisav] suggested (see link to mailing list below) root cause of the bug may be that current implementation handles EVT_NODE_LEFT and EVT_NODE_FAILED events in the same way and puts semaphore to a broken state.

h4. Steps to reproduce
# Using *ExampleNodeStartup* class start two or more server nodes.
# Using *IgniteSemaphoreExample* class run example and let it finish (it should finish normally and then terminate).
# Run *IgniteSemaphoreExample* once again.

h4. Expected behavior
Second execution of the same example finishes successfully.
h4. Actual behavior
Second execution hangs forever, node running example never finishes.
