Summary: Fix flapper test
MetaDataCacheMetricsIT.testGlobalClientCacheMetricsOfCreateAndDropTable
Key: PHOENIX-7746
URL: https://issues.apache.org/jira/browse/PHOENIX-7746
Project: Phoenix
Issue Type: Improvement
Affects Versions: 5.3.0, 5.2.1, 5.4.0
Reporter: Tanuj Khurana
Assignee: Tanuj Khurana
By default, we query SYSTEM.TASK after an initial delay of 10 seconds. If the
test setup takes more than 10 seconds, the query on SYSTEM.TASK executes and
that messes up some of the metadata cache metrics because the test metrics
don't account for that query. We are seeing this lately because in 5.3 we are
creating more system tables related to CDC streams. On the PHOENIX-7562 feature
branch we are hitting this often because there we have added another system
table.
An easy way to repro this is to add a Thread.sleep > 10 seconds in the failing
test right before the assert check that is failing.
