我是新来的oozie，我正在尝试安装和安装oozie。我遵循apache网站上提供的说明：“http://oozie.apache.org/docs/3.3.2/dg_quickstart.html#building_oozie". 我已经完成了以下工作：
构建分发服务器 ./mkdistro.sh -DskipTests .
下载了extjs2.2并分解成一个libext文件夹
我已经安装了hadoop1.1.2，并在aws示例中使用了ubuntu12.04。
在我学习的过程中，集群被设置为伪分布式的
使用以下配置更新了core-site.xml：

<property>
    <name>hadoop.proxyuser.ubuntu.hosts</name>
    <value>*</value>
</property>
<property>
    <name>hadoop.proxyuser.ubuntu.groups</name>
    <value>*</value>
</property>

执行 oozie-setup.sh prepare-war -hadoop $HADOOP_HOME 0.20.2 -extjs libext 收到消息“oozie准备启动”
执行 ooziedb.sh create -sqlfile oozie.sql -run . 数据库创建成功。
执行

oozied.sh start

没有错误报告，只是打印了变量值。
我打开了门 catalina.out 文件，我看到以下消息：

ERROR: Oozie could not be started 

REASON: org.apache.oozie.service.ServiceException: E0000: System property 'oozie.home.dir' not defined

堆栈跟踪：

org.apache.oozie.service.ServiceException: E0000: System property 'oozie.home.dir' not defined
        at org.apache.oozie.service.Services.setOozieHome(Services.java:80)
        at org.apache.oozie.service.Services.<init>(Services.java:101)
        at org.apache.oozie.servlet.ServicesLoader.contextInitialized(ServicesLoader.java:38)

有人能帮我弄清楚 oozie.home.dir 需要设置属性？
