Question

几天前，我在我的机器（Ubuntu）上提取了Spark并进行了测试，一切看起来都很好。今天，我想我改变了一些Java路径，现在Spark不会启动相反，我收到以下错误消息：

user@user:~/Software/spark-1.1.0-bin-hadoop2.4$ ./bin/pyspark

使用Eclipse运行Java程序仍然有效。

修改

which java: /usr/bin/java
javac -version: javac 1.7.0_65
echo $JAVA_HOME: /usr/lib/jvm/java-7-sun/bin

Answer 1

您的错误消息包含路径/usr/lib/jvm/java-7-sun/bin/bin/java。请注意重复的bin片段。

bin不得成为JAVA_HOME的一部分，请将其设为/usr/lib/jvm/java-7-sun/。

无法运行Spark
