我在CentOS 7.0上安装hadoop 2.5.1。
(1)当我在hadoop上运行应用程序时,我对消息路径感到怀疑" /tmp/hadoop-yarn/staging/hadoop/.staging/job_1424775783787_0001/files"是由兼容性引起的。 如果它的兼容性问题,那我怎么能修补这个??
15/02/24 20:27:41 ERROR streaming.StreamJob:错误启动工作: 文件/tmp/hadoop-yarn/staging/hadoop/.staging/job_1424775783787_0001/files/Formatter.sh只能复制到0个节点而不是minReplication(= 1)。有0个数据节点在运行,并且在此操作中不排除任何节点。
(2)端口主站:9000正在侦听,但是datanode没有连接到master, 但是nodemanager还活着。 所以我可以检查8088端口的活动数据节点 但它没有检查50070端口
配置如下所示。

答案 0 :(得分:0)
以下步骤应解决此问题。 但是,您可能会丢失数据。
停止Hadoop:
删除NameNode&amp; DataNode:
格式化NameNode
启动NameNode,Datanodes&amp; YARN
