[jira] [Created] (CASSANDRA-14244) Some tests in read_repair_test are flakey

Sam Tunnicliffe created CASSANDRA-14244:
-------------------------------------------

             Summary: Some tests in read_repair_test are flakey
                 Key: CASSANDRA-14244
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14244
             Project: Cassandra
          Issue Type: Test
          Components: Testing
            Reporter: Sam Tunnicliffe
            Assignee: Sam Tunnicliffe


Since being refactored for CASSANDRA-14134, {{test_alter_rf_and_run_read_repair}} and {{test_read_repair_chance}} in {{read_repair_test.TestReadRepair}} are flakey and regularly fail on all branches. The problem is that the inital setup of these two tests doesn't explicitly set the {{read_repair_chance}} or {{dclocal_read_repair_chance}} properties on the test table. As a consequence, read repairs are sometimes probabilistically triggered and query results don't match the expectations.
