Mirza Aliev updated IGNITE-17976:
---------------------------------
Description:
*Scenario*:
Start two nodes, populate data, stop node, try to {{table.keyValueView().get}}
value.
*Expected behaviour*:
Exception is thrown (we need to agree on the right exception)
*Actual behaviour*:
We can caught {{ReplicationTimeoutException}}, {{TransactionException}},
{{IgniteException}}. Sometimes we fail with {{NullPointerException}}, the
reason is because we can stop leader of some partition, and for two nodes it is
impossible to elect new leader, so we get null in {{InternalTableImpl#enlist}}
when we try to get {{{svc.refreshAndGetLeaderWithTerm();}}
The problem can be reproduced in the test
{{ItIgniteNodeRestartTest#testOneNodeRestartWithGap}}, which was muted using
this ticket.
