问题描述

针对退役的datanode节点，进行重新服役，在安装软件包阶段（installing selected parcels），卡在activating阶段不动了。

解决方法

查看正在服役的datanode节点安装包

备份重新服役节点的 /opt/cloudera 目录

$ mv /opt/clouder /opt/cloudera_bak20180615lqz

打包正常节点的 /opt/cloudera 目录，远程拷贝到该节点，重新添加该节点，问题解决。

但是访问cloudera manager的管理界面时，报 Local parcel repository path does not exist 错误，经查重新服役的该节点就是cloudera-scm-server服务所在节点，备份的之前的/opt/cloudera_bak20180615lqz目录下的文件分布如下：

从离线安装路径拷贝percel-repo文件夹下的文件到重新服役节点的相应目录下：

$ ll /var/www/html/el6

拷贝到 /opt/cloudera/parcel-repo目录下后 *sha1文件改为*sha文件就行，然后改变parcel-repo的所属用户和用户组，并新建csd文件夹，问题解决。
