--------------------------------------
Summary: Exchange on NodeLeft event hangs when cluster is in
transition state
Key: IGNITE-11574
URL: https://issues.apache.org/jira/browse/IGNITE-11574
Project: Ignite
Issue Type: Bug
Reporter: Ivan Bessonov
Assignee: Ivan Bessonov
Attachments: ExchangeDeadlockTest.java
The problem is in this code (GridCachePartitionExchangeManager#start0) :
{code:java}
if (cache.state().transition()) {
if (log.isDebugEnabled())
log.debug("Adding pending event: " + evt);
pendingEvts.add(new PendingDiscoveryEvent(evt, cache));
}{code}
Problem occurs when "setBaseline" and "nodeLeft" events happen simultaneously
(+ some undetermined conditions).
"nodeLeft" provokes exchange, and while that exchange isn't finished
"setBaseline" is invoked. This moves cluster into a transition state and
"CacheAffinityChangeMessage" from the exchange cannot be processed properly. At
the same time "setBaseline" cannot be completed before the exchange, so we have
a deadlock.
Reproducer attached.
