Description

I provide a simple example and used resource's picture for this issue 

this application is about flink consumer kafka,  when submit job such as : 

flink-1.7.1/bin/flink  run -m yarn-cluster -yn 1   -ynm test -p 5  -cMainConnect3  ./flinkDemo-1.0-SNAPSHOT.jar &

or 

flink-1.7.1/bin/flink  run -m yarn-cluster   -ynm test  -cMainConnect4  ./flinkDemo-1.0-SNAPSHOT.jar &

from yarn web ,i see, the total resources are erratic, and in most cases, all the remaining resources of the cluster will be used by the application
