I'm not an expert on YARN but I think we should not rely on the yarn's limitations here. Besides, if our assumption is that `yarnMinAllocationMB` should always be greater than 0, why do we set the default value as 0, which is obviously a wrong value and certainly crashes the job. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
