我正在构建一个由 2 个节点组成的小型 Hadoop 集群:1 个主节点 + 1 个工作节点。我正在使用最新版本的 Hadoop (3.2),一切都由root用户执行。在安装过程中,我已经能够hdfs namenode -format
. 下一步是使用start-dfs.sh
.
$ start-dfs.sh
Starting namenodes on [master]
bash v3.2+ is required. Sorry.
Starting datanodes
bash v3.2+ is required. Sorry.
Starting secondary namenodes [master]
bash v3.2+ is required. Sorry.
这是日志中生成的日志:

当我使用Zsh(使用Oh-my-Zsh)时,我登录到 bash 控制台试一试。可悲的是,我得到了同样的结果。实际上,所有sbin/start-*.sh
脚本都会发生此错误。然而,hadoop
andyarn
命令就像一个魅力。
由于我在互联网上没有找到有关此错误的太多信息,所以我在这里。很高兴有任何建议!
