错误：无法找到或加载主类 org.apache.spark.launcher.Main

Question

如果有人能帮我解决以下路径问题，我将不胜感激？我非常怀疑这与缺少路径设置有关，但不知道如何解决。

rxie@ubuntu:~/Downloads/spark$ echo $PATH
/usr/bin/java:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/rxie/Downloads/s                                                                                  park:/home/rxie/Downloads/spark/bin:/usr/bin/java
rxie@ubuntu:~/Downloads/spark$ pyspark

错误：无法找到或加载主类 org.apache.spark.launcher.Main

rxie@ubuntu:~/Downloads/spark$ spark-shell

错误：无法找到或加载主类 org.apache.spark.launcher.Main

rxie@ubuntu:~/Downloads/spark$ pwd /home/rxie/Downloads/spark

rxie@ubuntu:~/Downloads/spark$ ls
bin  conf  data  examples  jars  kubernetes  licenses  R  yarn

使用 PATH 更新：

rxie@ubuntu:~$ echo $PATH
/home/rxie/Downloads/spark:/usr/bin/java:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin
