src/main/java/org/apache/aurora/scheduler/app/SchedulerMain.java (lines 96 - 104) <https://reviews.apache.org/r/57061/#comment239113> Feels like a good place to add some context from the design doc here. E.g. why do we have multiple drivers? What are the implications of using each one? src/main/java/org/apache/aurora/scheduler/mesos/LibMesosLoadingModule.java (line 25) <https://reviews.apache.org/r/57061/#comment239114> Update this doc to reflect the new behavior? src/main/java/org/apache/aurora/scheduler/mesos/MesosSchedulerImpl.java (lines 387 - 399) <https://reviews.apache.org/r/57061/#comment239116> Seems like a good place to use a CacheBuilder (to avoid the String creation per event received). Also, we don't normally initialize counters to 0. Any particular reason why it's necessary here? src/main/java/org/apache/aurora/scheduler/mesos/VersionedSchedulerDriverService.java (line 48) <https://reviews.apache.org/r/57061/#comment239112> Missing Javadoc. src/main/java/org/apache/aurora/scheduler/mesos/VersionedSchedulerDriverService.java (lines 114 - 115) <https://reviews.apache.org/r/57061/#comment239111> Can we avoid repeating this in each method? - David McLaughlin On Feb. 28, 2017, 12:43 a.m., Zameer Manji wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
