Re: while setting database connection with mysql facing error

Hi @warrior ,

 

Could you please paste the documentation link which you were following to install Cloudera Manager? Here is the latest doc for your information:

https://www.cloudera.com/documentation/enterprise/latest/topics/install_cm_cdh.html

Also, did you install the JDBC driver on the CM host and all the other hosts which requires database access like this doc mentions?

Thanks,

Li
