Mirza Aliev updated IGNITE-19342:
---------------------------------
Description:
{{DistributionZoneManagerScaleUpTest#testUpdateZoneScaleUpTriggersDataNodePropagation}},
{{DistributionZoneManagerScaleUpTest#testUpdateZoneScaleDownTriggersDataNodePropagation}}
- this tests fail with the following assertion error: Expected revision that
is greater or equal to already seen meta storage events. This is because
TestConfigurationStorage does not use the same revision as the Meta Storage,
therefore their revisions can't be compared directly. This should use
`DistributedConfigurationStrorage` instead.
Also
{{DistributionZoneManagerScaleUpTest#testDropZoneDoNotPropagateDataNodesAfterScaleUp}},
{{DistributionZoneManagerScaleUpTest#testDropZoneDoNotPropagateDataNodesAfterScaleDown}}
failures can be fixed with the introduction of
{{DistributedConfigurationStrorage}} in the DistributionZoneManagerScaleUpTest
- this test is flaky, because notifications from test configuration storage and
from Meta Storage Watches are not related to each other (unlike real-life
Distributed Configuration Storage which is built on top of Watches), so
notifications from the configuration storage and Meta Storage can arrive in a
undetermined order.
