Apache spark SparkR和Pyspark在启动时抛出Java.net.Bindexception，但Spark Shell没有？

我已经尝试将SPARK_LOCAL_IP设置为“127.0.0.1”，并检查端口是否已被占用。以下是完整的错误文本：

以上错误发生在启动时。/bin/sparkR。火花壳将再次正常执行

更多信息。Spark shell在启动时将自动搜索端口，直到解决了一个没有绑定异常的端口。即使我将默认SparkR后端端口设置为未使用的端口，它也会失败

我发现了这个问题。另一个用户已删除我的etc/hosts文件。我用localhost重新配置了该文件，它似乎运行sparkR。我仍然很好奇spark shell是如何运行该文件的
