             Summary: Investigate setting discardCustomMsgId to null in prepareNodeAddedMessage
                 Key: IGNITE-11271
                 URL: https://issues.apache.org/jira/browse/IGNITE-11271
             Project: Ignite
          Issue Type: Improvement
            Reporter: Alexey Goncharuk


>From debugging IGNITE-10935 it was discovered that NodeAddedMessage contains wrong state:
pending messages are already filtered out by discard ID, but at the same time discardId and
customDiscardId are set to non-null values. This resulted in a broken pending messages iterator
on a newly added node: SkipIterator was skipping all pending messages until a valid discardId
was received.

The fix made in IGNITE-10935 was incomplete because we should have set both discardId and
customDiscardId to null. However, after running TC tests it turned out that setting discardCustomMsgId
to null resulted in duplicate custom events (the particular failed test is AuthenticationProcessorNodeRestartTest#testConcurrentAddUpdateRemoveNodeRestartServer)

The reason behind the failed test is that some of the fired custom events are delivered multiple
times. This should be investigated.
