在我的windows机器上，我正在尝试使用spark 2.4.6而不使用hadoop，使用-spark-2.4.6-bin-without-hadoop-scala-2.12.tgz
在设置了spark\u home、hadoop\u home和spark\u dist\u类路径之后，这里链接了文章中的信息
当我试图启动Spark壳，我得到这个错误-

上面引用的链接似乎指向spark\u dist\u类路径，但我的系统变量中已经有了这个链接-
$hadoop\u主页$hadoop_home\etc\hadoop*$hadoopïhome\share\hadoop\common\lib*$hadoop\u主页\共享\ hadoop\common*$hadoopïhome\share\hadoop\hdfs*$hadoop\u home\share\hadoop\hdfs\lib*$hadoopïhome\share\hadoop\hdfs*$hadoopïhome\share\hadoop\yarn\lib*$hadoopïhome\share\hadoop\yarn*$hadoopèhome\share\hadoop\mapreduce\lib*$hadoopïhome\share\hadoop\mapreduce*$hadoopïhome\share\hadoop\tools\lib*；
我在spark的spark-env.sh中也有这一行-

export SPARK_DIST_CLASSPATH=$(C:\opt\spark\hadoop-2.7.3\bin\hadoop classpath)

HADOOP_HOME = C:\opt\spark\hadoop-2.7.3
SPARK_HOME = C:\opt\spark\spark-2.4.6-bin-without-hadoop-scala-2.12

当我尝试hadoop附带的spark2.4.5时，它似乎运行得很好。这告诉我hadoop的设置方式有问题。我错过了什么？谢谢！
