当我用执行spark-submit命令时 - master yarn-cluster --num-executors 7 --driver-memory 10g --executor-memory 16g --executor-cores 5 ，我得到以下错误，我不知道在哪里更改堆大小，我怀疑Yarn配置文件在某处，请建议
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.**
