src/main/python/apache/aurora/executor/common/health_checker.py (line 137) <https://reviews.apache.org/r/51876/#comment216446> It seems to me the order doesn't matter that much. However, I still have the feeling that Maxim's proposal makes the expiration and failure count more close to their true definition, and less ambuiguous. The tests should not dictate how we write the source code. Sometimes we have to refactor them. Please feel free to weigh in. - Kai Huang On Sept. 14, 2016, 4:43 a.m., Kai Huang wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
