hadoop - Hadoop 2.6多节点集群

标签 hadoop high-availability

我有2个namenodes和4个datanodes.namenodes本身充当datanode并且还专用2个其他datanodes。

lsof -i:2181 -s

它在namenode1上显示namenode1 / x.x.x.x-> namenode1并且
namenode2 / x.x.x.x-> namenode2在namenode2上。
当我通过杀死activ namenode的pid来检查自动故障转移时，两个Web UI均停止并显示hadoop dfwsadmin -report的错误日志是
在namenode2 == >>>
