Stevo Slavic commented on ZOOKEEPER-2272:
-----------------------------------------
There should be more thorough cleanup of configuration management code and
documentation. Seems every class implements it's own way of obtaining
configuration and as consequence there's lots of inconsistency. E.g. in
{{ZooKeeperServer}} __allowSaslFailedClients__ is __true__/__false__, while in
{{PrepRequestProcessor}} __skipACL__ is __yes__/__no__
Some properties are defined via config file, some via system properties but not
both. Because of lack of consistency or even proper configuration design, that
inconsistency is reflected in poor documentation as well.
For good configuration design, implementation and documentation ideas please
have a look at Apache Kafka (especially bit where they generate configuration
documentation from source), Apache Commons Configuration
({{AbstractConfiguration}} abstraction, extended in Netflix Archaius Core with
{{DynamicPropertyFactory}}), and Spring framework {{PropertySource}}
abstraction.
