throttle consumer timeout increase (#8188)
The test_throttled_reassignment test fails because the consumer that is used to validate reassignment does not start on time to consume all messages. This does not seem like an issue with the throttling of the reassignment, since increasing the timeout allowed the test to pass multiple consecutive runs locally. This test seemed to rely on the default JmxTool for the console consumer that was removed in this commit: 179d0d7 The console consumer would check to see if it had partitions assigned to it before beginning to consume. Although the test occasionally failed with the JmxTool, it began to fail much more after the removal. Error messages of failures followed the below format with varying numbers of missed messages. They are the first messages by the producer. 535 acked message did not make it to the Consumer. They are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19...plus 515 more. Total Acked: 192792, Total Consumed: 192259. We validated that the first 535 of these missing messages correctly made it into Kafka's data files. This suggests they were lost on their way to the consumer. In the scope of the test, this error suggests that the test is falling into the race condition described in produce_consume_validate.py, which has the timeout to prevent the consumer from missing initial messages. This can serve as a temporary fix until the logic of consumer startup is addressed further. Reviewers: Jason Gustafson <[email protected]>, Bill Bejeck <[email protected]>
