我在Hadoop2.2集群上安装了Oozie4.0.1。之后，我尝试运行oozie作业（java操作）。一切似乎都很好：
当我运行job.properties时，它会像往常一样给出作业id。
当我检查oozie控制台作业是否处于运行状态时。
它运行java代码。
但是，oozie突然停止并显示以下错误。

如果您使用的是hadoop-2.2.0，则必须启动job historyserver以避免上述错误。
默认情况下，historyserver位于hadoop/sbin中。在启动hadoop时，jobhistory服务器有时无法运行，因此必须使用下面的命令手动启动jobhistory服务器。

hadoop/sbin/mr-jobhistory-daemon.sh start historyserver
