折腾几天，终于装好了Oozie 5.0.0，并且启动了Oozie守护进程。
vagrant@node1:~$ oozie admin -oozie http://10.211.55.101:11000/oozie -status
log4j:WARN No appenders could be found for logger (org.apache.hadoop.security.authentication.client.KerberosAuthenticator).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
System mode: NORMAL
不过运行MapReduce demo总是出错，找不到Oozie的共享库，日志如下：

折腾了无数次oozie-setup.sh sharelib命令，root和vagrant用户都试过。还在oozie-site.xml中指定了oozie.service.WorkflowAppService.system.libpath属性。结果统统失败。
vagrant@node1:~$ sudo -sE
root@node1:~#/usr/local/oozie/bin/oozie-setup.sh sharelib create -fs hdfs://10.211.55.101 -locallib /usr/local/oozie/oozie-sharelib-5.0.0.tar.gz
root@node1:~#/usr/local/oozie/bin/oozied.sh start
root@node1:~#exit
vagrant@node1:~$ oozie admin -configuration | grep oozie.service.WorkflowAppService.system.libpath
oozie.service.WorkflowAppService.system.libpath : /user/root/share/lib
vagrant@node1:~$ oozie admin -shareliblist -oozie http://localhost:11000/oozie
[Available ShareLib]
之后找到了Oozie/OOZIE-3208 “It should never happen” error messages should be more specific to root cause，不过就是改善一下错误消息并且在5.1.0里发布，还是没找到问题所在。
再之后发现自Oozie4.2.0开始oozie.service.WorkflowAppService.system.libpath的默认值变了：
将oozie-site.xml中oozie.service.WorkflowAppService.system.libpath属性值改为hdfs://10.211.55.101/user/root/share/lib，结果出错信息变成了"IllegalArgumentException: Wrong FS: hdfs://10.211.55.101/user/root/share/lib, expected: file:///"。

最后在oozie-site.xml添加了oozie.service.HadoopAccessorService.hadoop.configurations属性值*=/usr/local/hadoop/etc/hadoop/，终于可以找到共享库了：
vagrant@node1:~$ oozie admin -shareliblist

distcp
