[jira] [Commented] (CASSANDRA-14571) Fix race condition in MV build/propagate when there is existing data in the base table

    [ https://issues.apache.org/jira/browse/CASSANDRA-14571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17125887#comment-17125887 ] 

Berenguer Blasi commented on CASSANDRA-14571:
---------------------------------------------

Looking at 4.0 test failures this one was failing again. There is still a window for schema agreement to happen but the view not be available yet in some nodes. Marking the flaky test in CASSANDRA-15855 and CASSANDRA-15845 to address that root cause eventually. #justfyi

> CASSANDRA-13426 exposed a race in MV initialisation and building, which now breaks, consistently, {{materialized_views_test.py::TestMaterializedViews::test_populate_mv_after_insert_wide_rows}}.
> CASSANDRA-14168 is also directly related.
