我正在尝试在我的Hadoop集群(Ubuntu 14.04)上安装最新版本的Cloudera管理器,按照以下步骤操作。我将 Ubuntu Trusty Cloudera Manager 列表文件移动到/etc/apt/sources.list.d/
目录中,没有意识到其他人也已经将 Ubuntu Precise 列表移到了那里。我尽可能多地完成了安装,现在在Oozie上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
使用的是精确安装,而oozie-client
使用的是Trusty安装。我无法删除它们中的任何一个(purge
给出了类似的结果):
% 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,我总是收到奇怪的Oozie依赖项错误。思潮?
其中一个较旧的sources.list文件中有一个拼写错误。一旦它被替换,我就能够运行 apt-get 更新,然后给出不同的错误。 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 并取出给出语法错误的行。最后,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。
