从现在开始，我就在Mac上使用Hadoop(CDH 4.5)，并定期运行map reduce作业。我最近按照以下说明安装了oozie(再次为CDH4.5):
http://archive.cloudera.com/cdh4/cdh/4/oozie-3.3.2-cdh4.5.0/DG_QuickStart.html，并尝试运行提供的示例程序。但是，它总是失败，并显示以下错误。看起来工作流根本没有运行。作业信息中的控制台URL字段也为空。
有人可以帮忙吗？
以下是Oozie作业日志的相关代码段。

最佳答案
您是否已使用MapReduce或YARN设置hadoop？
Configuring which Hadoop Version to Use
The Oozie client does not interact directly with Hadoop MapReduce, and so it does not require any MapReduce configuration.
The Oozie server can work with either MRv1 or YARN. It cannot work with both simultaneously.
The MapReduce version Oozie server works with is determined by the CATALINA_BASE variable in the /etc/oozie/conf/oozie-env.sh file. By default, CATALINA_BASE is set to /usr/lib/oozie/oozie-server-0.20. This setting configures the Oozie server to work with MRv1.
To configure the Oozie server to work with YARN instead, set CATALINA_BASE to /usr/lib/oozie/oozie-server.
由于您拥有cdh4发行版，因此请在此链接http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Installation-Guide/cdh4ig_topic_17.html之后安装oozie
如果您有YARN，请在job.properties中更改jobtracker的端口
nameNode=hdfs://localhost:8020
jobTracker=localhost:8021
代替端口8021(jobTracker)，使用资源管理器的端口:8032
jobTracker=localhost:8032
