Todd Lipcon created KUDU-2717:
---------------------------------
Summary: Add an environment variable for username override in
non-secure clusters
Key: KUDU-2717
URL: https://issues.apache.org/jira/browse/KUDU-2717
Project: Kudu
Issue Type: Improvement
Components: security, util
Reporter: Todd Lipcon
If a cluster isn't secure, then using the current Unix username isn't a strong
identity. However, we still perform authorization based on that username. This
makes it inconvenient to run tools like 'ksck' from a regular user account --
you end up needing to 'sudo -u kudu' before doing so, and if running from a
remote machine there might not even be such a user.
Given that the local username isn't a strong identity anyways (someone could
always recompile kudu or use LD_PRELOAD to override it), let's provide an
environment variable KUDU_USER_NAME that can perform a similar override.
