在 Hadoop 中设置集群 - JPS 不显示 NodeManager 和 ResourceManager
Setting up a cluster in Hadoop - JPS does not show NodeManager and ResourceManager
我正在尝试在伪分布式模式下配置 Hadoop。 start-dfs.sh 完美运行。 jps 给出以下输出（正确启动所有守护进程）：
26051 NameNode
26533 SecondaryNameNode
29381 Jps
26237 DataNode
但是，start-yarn.sh无法启动nodemanager和resourcemanager。 jps 给出与使用 start-dfs.sh:
后相同的输出
26051 NameNode
26533 SecondaryNameNode
29381 Jps
26237 DataNode
resourcemanager 的日志文件提供以下内容：
