java - 安装后尝试打开spark并收到错误: Unable to find any JVMs matching version "1.8"

Question

描述:

我使用 Homebrew 在 MacBook 上安装了 Spark。我按照以下指示流程进行操作:https://www.tutorialkart.com/apache-spark/how-to-install-spark-on-mac-os/ 。

分步过程包括安装 Java，然后是 Scala，然后是 Spark。 Java和Scala安装成功。 Spark也安装成功了。

当我尝试使用以下输入命令验证 Spark 安装时，遇到了错误。

输入命令: spark-shell

预期行为:期望 Spark 在终端上启动

实际行为:我收到以下错误:

Unable to find any JVMs matching version "1.8".

我尝试过的:

我尝试使用以下命令更改 JAVA_HOME:

export JAVA_HOME=/usr/local/opt/java

以前的 JAVA_HOME 路径是 /opt/anaconda3。我可以看到 JAVA_HOME 已更改为 usr/local/opt/java 。

我仍然收到错误。感谢您的回答/反馈。谢谢!!!

对于 macOS，请执行以下步骤步骤 1. 安装 java 8，因为 Spark 2.2 及以上版本需要 java8。请参阅Spark Documentation !了解详情。

brew install openjdk@8

然后设置更新java路径

export JAVA_HOME=/usr/local/opt/openjdk@8/libexec/openjdk.jdk/Contents/Home
