CDH Executing: /usr/java/jdk1.8.0_181-cloudera/bin/java -cp :/opt/cloudera/cm/schema/../lib/* com.c

一、报错（安装cdh）

1、系统环境

系统：CentOS7.8
数据库：MySQL5.7

2、错误

3、解决方案(缺少MySQL驱动包)

ln -s /usr/share/java/mysql-connector-java-5.1.47.jar ./mysql-connector-java.jar

[root@cdh-cm-v01 lib]# ln -s /usr/share/java/mysql-connector-java-5.1.47.jar ./mysql-connector-java.jar
