------------------------------------------
Summary: NPE when some operation pocessed when the primary replica
is changeing
Key: IGNITE-20484
URL: https://issues.apache.org/jira/browse/IGNITE-20484
Project: Ignite
Issue Type: Bug
Reporter: Vladislav Pyatkov
It happens that when the request is created, the primary replica is in this
node, but when the request is executed in the replica, it has already lost its
role. In this case, we should throw the correct exception because the request
cannot be handled in this replica anymore, and the matched transaction will be
rolled back.
