CDH6.3.2安装cloudera-manager-daemons出现JDK版本不兼容问题

如题，今天在测试环境安装CDH6.3.2时，执行

rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm，

输出以下错误：

仔细检查主机的jdk版本为1.8.0_181

[root@i-erwppify software]# echo $JAVA_HOME
/software/jdk1.8.0_181
[root@i-erwppify software]# which java
/software/jdk1.8.0_181/bin/java

按照CDH官网提示，也是建议这个版本的

 注意:Cloudera Manager会在启动时找到Oracle JDK ，无论您是否使用二进制|安装JDK ，安装程序或基于rpm的安装程序，基于这个原因，我们使用CDH提供的jdk版本重新安装jdk吧

rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm

安装后，再执行

rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm

可以看到执行没有问题了
