Question

我尝试启动hadoop，但失败，但未启动任何东西。遵循控制台日志。

Mac:sbin lqs2$ sh start-all.sh
/Users/lqs2/Library/hadoop-3.1.1/libexec/hadoop-functions.sh: line 398: 
syntax error near unexpected token `<'

我尝试了任何方法来解决它，但是什么也没做。甚至我重新安装了最新版本。但是错误是相同的。这几乎使我发疯。

任何答案都是有帮助的。谢谢。

Answer 1

Hadoop脚本需要bash而不是sh

$ chmod +x start-all.sh
$ ./start-all.sh

尽管我建议分别启动HDFS和YARN，以便您可以隔离其他问题

您还需要将Hadoop至少降级到最新的2.7版本，Spark才能正常工作

使用hadoop-functions.sh启动hadoop失败
