java - spark-3.0.1-bin-hadoop2.7无法启动，java:无此文件或目录

Question

每当我使用Java时，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

Answer 1

java.exe在您的输出中确实存在
您已经安装了Java for Windows，但是使用的Shell脚本无法一起使用。
