ubuntu - 尝试安装Cloudera Manager 5时Oozie依赖性不正确

Question

我正在尝试在Hadoop集群(Ubuntu 14.04)上安装最新版本的Cloudera Manager，即following these steps。我将Ubuntu Trusty Cloudera Manager列表文件移至/etc/apt/sources.list.d/目录，但没有意识到其他人也已经将Ubuntu Precise列表移至那里。我进行了尽可能多的安装，现在在Oozie中遇到了一些奇怪的依赖错误:

% sudo apt-get install cloudera-manager-daemons
Reading package lists... Done
Building dependency tree       
Reading state information... Done
cloudera-manager-daemons is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 oozie : Depends: oozie-client (= 3.1.3+155-1.cdh4.0.1.p0.1~precise-cdh4.0.1) but 4.1.0+cdh5.6.0+235-1.cdh5.6.0.p0.108~trusty-cdh5.6.0 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

当我列出已安装的Oozie软件包时，我得到:

% dpkg --list | grep "oozie"                                          
ii  oozie                               3.1.3+155-1.cdh4.0.1.p0.1~precise-cdh4.0.1            all          A workflow and coordinator sytem for Hadoop jobs.
ii  oozie-client                        4.1.0+cdh5.6.0+235-1.cdh5.6.0.p0.108~trusty-cdh5.6.0  all          Client for Oozie Workflow Engine

因此oozie使用的是Precise安装，而oozie-client使用的是Trusty安装。我无法删除其中任何一个(purge给出类似的结果):

% sudo apt-get  remove oozie-client                                 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 oozie : Depends: oozie-client (= 3.1.3+155-1.cdh4.0.1.p0.1~precise-cdh4.0.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

如果我尝试继续安装Cloudera，我会不断收到奇怪的Oozie依赖错误。有什么想法吗？

Answer 1

原来，其中一个较旧的sources.list文件中有一个错字。一旦替换了它，我便能够运行apt-get update，然后给出了另一个错误。看起来它正在尝试停止oozie服务并遇到语法错误。运行服务oozie stop给出了相同的错误。然后进入initscript /etc/init.d/oozie并取出出现语法错误的行。最终，我能够运行apt-get更新，卸载冲突的oozie版本并重新安装Trusty版本。
