Hello,

I have installed mysql database as external database and I'm trying to run scm_prepare_database.sh script and I get this error;

Hello,

I dont know how exactly I can use the test code. I dont have java know-how.

Thanks,

@Huriye,

You can also review tcpdump output to see if a conneciton is being made.  Check your mysql logs to see if a connection attempt is registered, etc.

Somewhere between the JDBC driver and your mysql server there is a failure of some sort, so diagnostics need to be performed to figure out what is failing.

This may take some digging, so if you have friends, colleagues, etc. who can work with you on this system and know how to debug these sort of connection issues, I'd ask them for some help.

I was suggesting the java app to test as an example of something you might try, but if it is outside your skillset, then there may be other ways.

Start by seeing if you can determine if the JDBC connection is able to reach its destination (mysql server).

Hello,

I resolved the error which wasa "Unable to find jdbc" by defining the full jar file name in /etc/defaul/cloudera-scm-server. But now I am getting another issue which is;

I have changed the password and tried again but getting the same error. 

Could you help me on this please?

Thanks,

@Huriye,

I could be wrong, but now it appears to be breaking earlier (before a connection is attempted).

Also, I note dthat you are using mysql-connector-java-8.0.11.jar which we do not currently support and we know will cause problems if you are able to get past this problem.  What command line did you use to generate this error... it appears the error is saying there is a problem with the syntax of the query and the query is generated based on the options you supplied.  Is it possible you have mismatched quotes around your password?

[#6]

Hello,

I changed the jar file name as mysql-connector-java.jar then I get error which password is not suitable for the policy. But removed my redhat machines and created Centos. Now I dont have any error to connecting mysql database. 

I still dont know what was the problem.

Thanks,

Huriye
