在hadoop3.0.0-cdh6.2.0的集群上，我试图通过oozie工作流的shell操作来运行docker容器。
docker正确安装在集群的每个节点上。如果我通过ssh连接到一个节点并尝试启动docker命令，那么一切都正常工作。我想安排我可以用oozie手动完成的事情，让它在集群的一个节点上打开一个shell并运行一些docker命令。
如果我尝试启动一个简单的docker命令 docker ps 或者 docker run hello-world 在shell操作或oozie启动的bash脚本中，作业失败，我可以从应用程序日志中检索到的错误是：

Failing Oozie Launcher, Main Class [org.apache.oozie.action.hadoop.ShellMain], exit code [1]

我尝试过的在stdoutput中给出预期结果的命令只有 docker version 以及 docker help . 我不明白为什么我可以在shell上手动执行的操作在oozie启动时不起作用。
