当我在cdh簇上启动h2o时,我得到以下错误。我下载了网站上的所有内容,并按照教程进行操作。我执行的命令是
hadoop jar h2odriver.jar -nodes 2 -mapperXmx 1g -output hdfsOutputDirName
它表明容器没有被使用。现在还不清楚这些在hadoop上是什么设置。我已经给了所有的设置记忆。内存的0.0没有意义,为什么容器不使用内存。集群现在还在运行吗?

您应该设置默认队列,使其具有运行2nodes集群的可用资源。
请参见警告:
WARNING: Job memory request (2.2 GB) exceeds queue available memory capacity (0.0 GB)
您要求每个节点1gb(+开销),但队列中没有可用的资源WARNING: Job virtual cores request (2) exceeds queue available virtual cores capacity (0)
您请求2个虚拟核心,但默认队列中没有可用的核心请检查Yarn文档-例如容量计划程序和最大可用资源的设置:https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/capacityscheduler.html
