我试图设置群集hadoop环境但无法启动从属数据节点。
以下是来自主节点的日志 -
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

hduser@vagrant:/usr/local/hadoop/sbin$ jps
3527 SecondaryNameNode

5633 NameNode

从上面的日志看起来它似乎已经开始，但这里是从节点jps命令 -
hduser@vagrant:/usr/local/hadoop/logs$ jps
3135 Jps
没有看到datanode正在运行。

看起来你没有把你的奴隶地址放在/ etc / hosts中。看看这个。如果没有问题，请检查奴隶的日志。
