Exceptions in static code blocks are really confusing to debug. I
personally would prefer to see a static function to get the log dir, that
caches the saved result.
> port backtype.storm.config to java

> Key: STORM-1227
> URL: https://issues.apache.org/jira/browse/STORM-1227
> Project: Apache Storm
> Issue Type: New Feature
> Components: storm-core
> Reporter: Robert Joseph Evans
> Assignee: Zhuo Liu
> Labels: java-migration, jstorm-merger
>
> port backtype.storm.config to java. There are some parts of this that for
> convince sake may need to stay in clojure, or have clojure equivalents.
> The code that turns Config.* into clojure constants needs to stay, and
> reading the config may need to stay in clojure until we can cleanup all of
> the places it is used to not need the migration.
