Is mySQL already installed on HDPCD Practice Exam instance? if yes, How to start mySQL in HDPCD Practice Exam instance?

You need to ssh onto the namenode first:

ssh root@namenode  (password is hadoop)

No need to start mysqld on the namenode - it's already running. You can view what's in the DB by running mysql:

# mysql --user root -p

Password is "hadoop". Let me know if that works.

Hi Rich,

As you suggested I have sent my Public DNS of my instance to certification@hortonworks.com

Thanks,

Ramesh.

Thanks. I logged in to it and everything looks fine. MySQL is running on the namenode, as expected, and I can run the mysql client to view the data in it.

Let me know if you need any further assistance.
