Sergey Chugunov created IGNITE-4209:
---------------------------------------
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.

behavior|http://apache-ignite-developers.2346864.n4.nabble.com/IGNITE-4155-IgniteSemaphoreExample-unexpected-behavior-td12077.html].
