工作者：無法通過Spark Apache連接到主服務器

Question

我試圖部署在Windows上使用獨立的集群管理器中的星火應用，所以在主端（IP：192 .186），我跑：

\\bin>spark-class org.apache.spark.deploy.master.Master

在從屬端（IP：192 . .75），我跑了：

\\bin>spark-class org.apache.spark.deploy.worker.Worker spark://192.*.*.186:7077

我有一個問題，客戶端無法連接到主節點，這是我得到的錯誤：

我怎樣才能解決這個問題？

Answer 1

bin>spark-class org.apache.spark.deploy.worker.Worker spark://192.*.*.186:7077

上面命令中提到的master-ip是否正確？

您寫道主ip是192 ... 168，但是在從屬啟動命令中您嘗試使用192 。 。 186 ，錯別字：倒6和8
