```
user configures export ZEPPELIN_IMPERSONATE_CMD in here with kinit
<principal>@<REALM> -k -t <keytab file> and then it's run before spark-submit
```
One concern is that this requires all the interpreters of one user share
the same keytab/principal. e.g. spark interpreter may affect shell interpreter
if they use different keytab/principal for the same user. For the long term, we
may need to put security related settings in one central place rather than in
each interpreter setting.
