Apache spark 主服务器未启动。引起：java.lang.reflect.InaccessibleObjectException

Question

我已经按照这些instructions 安装了 apache spark。当我进入第 5 步时，或者当我必须在终端中执行 start-master.sh 时，我会得到以下输出：

21/09/25 12:41:33 WARN Utils: Your hostname, petar-X580VD resolves to a loopback address: 127.0.1.1; using 192.168.0.105 instead (on interface wlp3s0)

我不知道如何解决这个问题。

正如@werner 在 cmets 中建议的那样，更改为 java 版本 11 解决了问题。
