Btw, for the hadoop case (or spark on yarn case), this PR may give an issue
for `doAs`.
Typically, you configure `hadoop.proxyuser.foo.hosts` and
`hadoop.proxyuser.foo.group`, `foo` being the os/kerberos user under which you
run your java code that calls doAs.
If we run ssh/su as the front-end user, we will not fullfill what the
hadoop/yarn cluster is expecting.
We thus should have two checkboxes:
- One for the OS/kerberos impersonation (this PR only adresses OS).
- The other for Hadoop impersonation.
If you select one, I would expect the other one to be disabled.
