Question

我是 Oozie 的新手，在 ubuntu 中使用 hadoop-2.2.0 构建 oozie-4.0.1 时遇到了很多问题。现在它是在这个 link 的帮助下构建的。我现在面临使用命令 bin/oozied.sh run 启动 oozie 的新问题。跟踪的错误显示：INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: 以及以下详细信息

错误：

我尝试了很多搜索上述错误，没有找到正确的错误，但找到了错误 Caused by: java.lang.UnsatisfiedLinkError: /usr/lib/java/jre/lib/i386/xawt/libmawt.so: libXi.so.6: cannot open shared object file: No such file or directory 的原因，这是由于 Ubuntu 64 位和 32 位 jdk 7。然后我重新安装 Ubuntu 32 位并按照对我有用的 link 上的步骤进行操作。谢谢...
