[jira] [Commented] (CASSANDRA-17649) Fix flaky tests in TopPartitionsTest

    [ https://issues.apache.org/jira/browse/CASSANDRA-17649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17568222#comment-17568222 ] 

Ekaterina Dimitrova commented on CASSANDRA-17649:
-------------------------------------------------

This seems to be a test issue.

Running the test class In a loop with only incremental repair was [always passing|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra?branch=basic-range-tombstone&filter=all]. 

The moment we run it parameterized, incremental and preview repairs seem to crash. Looking into the repair method in the test class, we see the nodetool  command was successfully triggered but we don't check that the repair has been completed.

I added some additional checks and the test seems not to be flaky anymore.

[~marcuse], do you mind to review the patch as the original author of this test? Or maybe [~dcapwell] ?
