Changing installation username from "cloudera-scm" to something else.

[#1]

Hi.

One of our customers asked us if it was possible to change the username of the CDH installation from "cloudera-scm" to another username. 

Is this possible without using single-user mode? I've searched in the internet but did not find anything related to this.

Thank you.

I think it's the copyright issue of cloudera. Modifications should not be allowed. Personal view only。。。

@JoaoBarreto,

It is possible to do so, but it is not something we document or test exactly.

The closest steps would be only doing the Cloudera Manager steps here:

https://www.cloudera.com/documentation/enterprise/5-15-x/topics/install_singleuser_reqts.html#concep...

Since the agent runs as "root" by default, you shouldn't need to do any of the agent-specific steps there.

Also, the Management Service "System User" and "System Group" are "cloudera-scm" by default.

You may need to do a little trial and error to get everything working, but I don't think it would be too bad.
