Re: Cloudera scm server start failed

Hello,

 

According to the error information it appears as though you are attempting to use mySQL as a database backend. The stack trace reports the the mySQL JDBC driver cannot be located or loaded.

 

 

HHH010003: JDBC Driver class not found: com.mysql.jdbc.Driver
...
Caused by: java.lang.ClassNotFoundException: Could not load requested class : com.mysql.jdbc.Driver

Please review the following documentation.
