尝试执行spark-shell时出现错误“无此文件或目录”

Question

我已经更新了jdk，现在当我尝试输入spark shell时，出现以下错误：

/home/orienit/work/spark-1.6.0-bin-hadoop2.6/bin/spark-class: line 86:  
 /usr/lib/jvm/java-1.8.0-openjdk/bin/java: No such file or directory

Answer 1

为了确保spark指向正确的Java版本： 1）转到{spark-dir}/conf 2）cp spark-env.sh.template spark-env.sh。 3）编辑“ spark-env.sh”并添加JAVA_HOME={JAVA_HOME_DIR} 4）执行-./spark-env.sh
