hadoop - 如何使用hadoop-2.2在oozie中执行mapreduce程序

Question

Ubuntu中的2.2.0和oozie-4.0.0。我无法在oozie中执行mapreduce程序。

我在oozie中使用jobtracker 8032的资源管理器端口号。

在安排一段时间后进入oozie进入运行状态并在 yarn 中运行时，我在hadoop日志中遇到了这样的错误(如下)，仍然在oozie日志中运行

错误:

我可以在oozie中运行java example(give in oozie)mapreduce程序。

如果我尝试运行pig，hive，sqoop或我自己的java mapreduce程序，则会收到上述错误，我不知道为什么会出现。我已经在oozie中给出了hadoop的配置路径，并且启动了我的工作历史服务器。

请帮帮我...

Answer 1

NodeManager和Resource Manager在同一系统中运行。所以我得到这个错误。我在第二个系统中启动了节点管理器，问题解决了。
