每当我接触java时，我都会遇到一些问题(要使用tensorflowonspark，我运行代码）
在windowpowershell，

export JAVA_HOME=/mnt/c/Program\ Files/Java/jdk1.8.0_261

 ${SPARK_HOME}/sbin/start-master.sh

starting org.apache.spark.deploy.master.Master, logging to /mnt/c/Users/MY_PATH/spark-3.0.1-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.master.Master-1-DESKTOP-5CGUHKF.out failed to launch: nice -n 0 /mnt/c/Users/MY_PATH/spark-3.0.1-bin-hadoop2.7/bin/spark-class org.apache.spark.deploy.master.Master --host DESKTOP-5CGUHKF.localdomain --port 7077 --webui-port 8080 /mnt/c/Users/MY_PATH/spark-3.0.1-bin-hadoop2.7/bin/spark-class: line 71: /mnt/c/Program Files/Java/jdk1.8.0_261/bin/java: No such file or directory ```
