[GitHub] [helix] kaisun2000 opened a new issue #1274: fix flaky test TestAutoRebalancce
kaisun2000 opened a new issue #1274:
URL: https://github.com/apache/helix/issues/1274
This one failed 3 times in github out of 10 logs examined.
```
Thread.sleep(100);
result = ClusterStateVerifier.verifyByPolling(
new ExternalViewBalancedVerifier(_gZkClient, CLUSTER_NAME, TEST_DB), 10000, 100);
Assert.assertTrue(result); ---> this line fails.
```
Maybe it did note wait log enough for this ExternalViewBalancedVerifie. Need to add a log for distinguish the failure cause.

Close test unstable tickets since we have an automatic tracking mechanism https://github.com/apache/helix/pull/1757 now for tracking the most recent test issues.

Wait longer before polling to cluster converge and using correct AutoRebalancer class with AutoRebalancer strategy

This could be similar to https://github.com/apache/helix/issues/1268. Though validation is not easy. Maybe by reducing the ExternalViewBalancedVerifier polling time out, if it fails consistently, we can confirm.
