cloudera manager 升级到jdk1.8

CDH5.11自带的是spark1.6，在把spark升级到2.2之后，添加服务，执行服务 Spark 2 上的命令 部署客户端配置阶段报错。

“客户端配置 (id=2) 已使用 1 退出,而预期值为 0

我们可以看到，spark2.2需要jdk1.8版本，而系统自带的是jdk1.7.0_67， 看起来解决任务只是把jdk版本升级就好，于是，我把CDH集群中的jdk都升级到了jdk1.8.0_60, 顺便提一句，spark2.2 需要scala2.11以上版本。

1. 停掉cloudera manager

2. 停掉服务器服务

   /opt/cm-5.11.0/etc/init.d/cloudera-scm-server stop

3. 关闭所有客户端服务

   /opt/cm-5.11.0/etc/init.d/cloudera-scm-agent stop

4. 卸载原本的jdk

5. 安装新的jdk，并配置JAVA_HOME

   vim /opt/cm-5.11.0/etc/default/cloudera-scm-server
   export JAVA_HOME=/usr/java/jdk1.8.0_60

6. 开启所有服务

7. 启动cloudera manager

在每个主机上配置java home

8. 启动集群
