Spark:Initial job has not accepted any resources
我在本地寫了個 Spark 的 Driver,執行 local 模式沒問題,當把 master 改成了遠端的 spark://ip:7077 就會卡主,報下面這個 WARN:
Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources
到 Spark 介面上發現資源足夠,我也只是讀了個小的 csv 檔案,因此不是資源的問題,而是網路的問題,是 Spark 叢集的網路連線不到我的電腦。
打包放到 Spark 叢集上執行就可以了。
