当我用--master yarn cluster--num executors 7--driver memory 10g--executor memory 16g--executor cores 5执行spark submit命令时，我得到以下错误，我不确定在哪里更改堆大小，我怀疑yarn配置文件在什么地方，请给出建议
错误

Invalid maximum heap size: -Xmx10g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.**
