[jira] [Created] (FLINK-18067) Invalid default value for yarnMinAllocationMB in YarnClusterDescriptor

Jiayi Liao created FLINK-18067:
----------------------------------

             Summary: Invalid default value for yarnMinAllocationMB in YarnClusterDescriptor
                 Key: FLINK-18067
                 URL: https://issues.apache.org/jira/browse/FLINK-18067
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / YARN
    Affects Versions: 1.10.1
            Reporter: Jiayi Liao


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]:

* 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.
