steveloughran opened a new pull request #630: HADOOP-15999 improve test resilience and probes URL: https://github.com/apache/hadoop/pull/630 HADOOP-15999 improve test resilience and probes * Add delays long enough for timestamps to be different * Add delays for S3 to stabilize after writes/deletes, so that listings and HEAD calls will get the new value, not old ones * probes for differences look for file lengths ahead of timestamps, for more tangible failures. * and they validate the raw FS status acquired after the stabiliziation delay * package private (currently) probe for S3A to verify that an FS instances considers its store to be authoritative. Currently we've been checking the config, but to really know what's happening: lets query the internal state of FS.
