> Currently Flink sets {{yarnMinAllocationMB}} default value to 0, which will crash the job in normalizing the allocation memory. There should be two minor changes after discussion with [~fly_in_gis] in https://github.com/apache/flink/pull/11176#discussion_r433629963:
> * Make the default value to YarnConfiguration.DEFAULT_RM_SCHEDULER_MINIMUM_ALLOCATION_MB, not 0
> * Add pre-check for yarnMinAllocationMB, it should be greater than 0.
