BDE template default password

Essential role of the VMware Big Data Extension is the node provisioning automation function, which uses a virtual machine belonging to BDE’s vApp as template for new Hadoop cluster nodes.



It’s not unusual that companies need to change their template’s configuration to adhere to internal security requirements, installing agents like for  monitoring and antivirus or tweaking  some security parameter, which will all be inherited by the new nodes.

The template provided by VMware as part BDE 2.2 is a CentOS 6.5 64-bits, so if you want to change anything on it first you would need login on (obviously).
The thing is you can look for it's username and password through all the documentation and you wont find it.

Since it took me some time to find it, I thought it would be a good idea to share with you guys.

Without further ado here’s the BDE’s Hadoop template default password:

User: serengeti
Password: password

You can leverage sudo if you need to run any command with a higher privileges.

One last reminder, after your change is completed, don’t forget to remove all configs from /etc/sysconfig/network-scripts/ifcfg-eth (otherwise the new nodes wont get the correct IP) and delete the VM’s snapshot.

If you got this far and still have doubts about what BDE is really about, check my BDE The basics post.
