jiamei xie created KAFKA-9920:
---------------------------------

             Summary: Fix NetworkDegradeTest.test_rate test error
                 Key: KAFKA-9920
                 URL: https://issues.apache.org/jira/browse/KAFKA-9920
             Project: Kafka
          Issue Type: Bug
          Components: core, system tests
            Reporter: jiamei xie
            Assignee: jiamei xie


The test case of kafkatest.tests.core.network_degrade_test.NetworkDegradeTest.test_rate.
rate_limit_kbit=1000000.device_name=eth0.task_name=rate-1000-latency-50.latency_ms=50
failed. And the error log was "Expected most of the measured rates to be within an order
of magnitude of target 1000000. This means `tc` did not limit the bandwidth as expected."
It was because that the rate_limt didn't take immediately after starting.
