1 报错信息如下
+======================================================================+
| Error: JAVA_HOME is not set and Java could not be found |
+----------------------------------------------------------------------+
| Please download the latest Oracle JDK from the Oracle Java web site |
| > http://www.oracle.com/technetwork/java/javase/index.html < |
| |
| Cloudera Manager requires Java 1.6 or later. |
| NOTE: This script will find Oracle Java whether you install using |

2 但是自己设置了JAVA_HOME啊
3在CDH的cloudera-scm-server启动脚本中添加JAVA_HOME环境变量
find / -name 'cloudera-scm-server'
vim /etc/rc.d/init.d/cloudera-scm-server
export JAVA_HOME=/mnt/software/jdk1.8.0_201
重启OK，不再报错
