hadoop - Hadoop-DataNode未在从属服务器中运行

Question

我正在尝试设置集群hadoop环境，但无法启动从属服务器中的数据节点。

这是我来自主节点的日志-

hduser@vagrant:/usr/local/hadoop/sbin$ bash start-dfs.sh15/12/29 20:04:32 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Starting namenodes on [master]
master: namenode running as process 5633. Stop it first.
slave: starting datanode, logging to /usr/local/hadoop/logs/hadoop-hduser-datanode-vagrant.out
master: datanode running as process 3362. Stop it first.
localhost: datanode running as process 3362. Stop it first.

hduser@vagrant:/usr/local/hadoop/sbin$ jps
3527 SecondaryNameNode
3362 DataNode
5633 NameNode

在上面的日志中，它看起来像启动了，但是这是从节点jps命令-

hduser@vagrant:/usr/local/hadoop/logs$ jps
3135 Jps

没有看到datanode正在运行。

看来您没有将您的从属地址放在/ etc / hosts中。一探究竟。如果可以，请检查从站的日志。
