What if `yarnMinAllocationMB` equals to zero, which is the default value set
in
https://github.com/apache/flink/blob/03b82f9aa81b828b06c61f7f30f92a331ec5120b/flink-yarn/src/main/java/org/apache/flink/yarn/YarnClusterDescriptor.java#L511
I think we can add a pre condition here:
```
if (yarnMinAllocationMB == 0) {
return;
}
```
