Let's do test again. ``` FAIL: test_training_and_prediction (pyspark.mllib.tests.test_streaming_algorithms.StreamingLogisticRegressionWithSGDTests) Test that the model improves on toy data with no. of batches ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/jenkins/workspace/SparkPullRequestBuilder/python/pyspark/mllib/tests/test_streaming_algorithms.py", line 367, in test_training_and_prediction self._eventually(condition, timeout=60.0) File "/home/jenkins/workspace/SparkPullRequestBuilder/python/pyspark/mllib/tests/test_streaming_algorithms.py", line 69, in _eventually lastValue = condition() File "/home/jenkins/workspace/SparkPullRequestBuilder/python/pyspark/mllib/tests/test_streaming_algorithms.py", line 362, in condition self.assertGreater(errors[1] - errors[-1], 0.3) AssertionError: -0.070000000000000062 not greater than 0.3 ---------------------------------------------------------------------- Ran 13 tests in 184.315s FAILED (failures=1, skipped=1) ```
