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. We should use
{{DistributedConfigurationStrorage}} instead, so configuration will use the
same revisions, as the metastorage.
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.
Also
{{DistributionZoneManagerWatchListenerTest#testDataNodesOfDefaultZoneUpdatedOnWatchListenerEvent}}
could be fixed after introduction of {{DistributedConfigurationStrorage}} in
DistributionZoneManagerWatchListenerTest - this test is flaky, probably due to
some races between Watch and Configuration Listener execution (sometimes a
retry on invoke happens and Mockito#verify fails).
Test
{{DistributionZoneManagerScaleUpTest#testDataNodesPropagationAfterScaleUpTriggered}}
could fail with
{noformat}
java.lang.AssertionError:
Expected: is <1L>
but: was <3L>

This highly likely connected to the fact, that metastorage and configuration do
not share the same storage
