在 hdfs 中创建 Oozie sharelib。（Root 无法模拟 root）

Question

我正在关注 http://hadooptutorial.info/apache-oozie-installation-on-ubuntu-14-04/ 安装 oozie 4.1.0 和 hadoop 2.7.2

构建成功，我可以通过发出此命令来创建 oozie war

hduser@master:~/oozie/oozie-bin$ sudo bin/oozie-setup.sh prepare-war

在 /home/hduser/oozie/oozie-bin/oozie-server/webapps/oozie 添加了 'ExtJS library, JARs' 的新 Oozie WAR 文件。war

信息：Oozie 已准备好启动

但是当我发出这个命令时，用于打包 sharelib 的命令出错了

hduser@master:~/oozie/oozie-bin$ sudo bin/oozie-setup.sh sharelib create -fs hdfs://master:9000

输出：

setting CATALINA_OPTS="$CATALINA_OPTS -Xmx1024m"
log4j:WARN No appenders could be found for logger (org.apache.hadoop.util.Shell).
log4j:WARN Please initialize the log4j system properly.

Error: User: root is not allowed to impersonate root

错误的堆栈跟踪是（用于调试目的）：

我也重新启动了我的 hadoop 集群，但没有成功。

这是我的核心-site.xml

 <property>
        <name>hadoop.proxyuser.hduser.hosts</name>
        <value>*</value>
 </property>

<property>
        <name>hadoop.proxyuser.hduser.groups</name>
        <value>*</value>
</property>

有人可以帮忙吗？

不要使用 sudo 创建 sharelib，它会起作用。

在 hdfs 中创建 Oozie sharelib。（Root 无法模拟 root）

Oozie sharelib creation in hdfs.(Root is not able to impersonate root)

hadoop

hdfs

oozie
