Michael Han commented on ZOOKEEPER-2843:
----------------------------------------

It's not about complicated vs simple solution, it's about doing the right thing and avoid
accumulating technical debt.

> The current handling of {{zookeeper.security.auth_to_local}} in {{KerberosName.java}}
only supports rules given directly as property value.
> These rules must therefore be given on the command line and:
> * must be escaped properly to avoid shell expansion
> * are visible in the {{ps}} output
> It would be much better to put these rules in a file and pass the file path as the property
value. We would then use something like {{-Dzookeeper.security.auth_to_local=file:/etc/zookeeper/rules}}.
> Note that using the {{file:}} prefix allows keeping backward compatibility.
