Hi All,
I am a new sahara user, and I download cdh plugin image from
http://sahara-files.mirantis.com/images/upstream/liberty/.
Unfortunately, When I try to create a cdh-5.4 cluster, the cloudera-manager
always fail to start. I ssh to the manager server, and try to start by hand,
the "cloudera-scm-server.log" shows following error:
org.hibernate.service.classloading.spi.ClassLoadingException: HHH010003: JDBC
Driver class not found: com.mysql.jdbc.Driver
I download the mysql driver and copy to "/usr/share/cmf/lib", it seems to
work, but to my surprise the service die after a while. I check the log again,
and find the following error:
org.hibernate.exception.GenericJDBCException: Could not open connection
java.sql.SQLException: Connections could not be acquired from the underlying
database!
I'm not sure if these is some bugs in the images or I miss some configurations.
Is anyone meet similar issue? How to fix this error without modify the image?
Thanks!
Regards,
Guangping Fu
