我们有带有以下详细信息的spark集群(所有机器都是linux redhat机器)
2 name-node machines
2 resource-manager machines
8 data-node machines ( HDFS file-system)
我们正在运行运行Spark Streaming应用程序
从毛线记录中，我们可以看到以下错误，例如:
yarn logs -applicationId application_xxxxxxxx -log_files ALL

我们可以看到-
8478399929292:-blk_1081495827_7755233不存在或不在 build 中但是毛线抱怨的原因可能是什么？
最佳答案
根据 yarn 文件
yarn logs -applicationId <Application ID> -am ALL
会更合适
