> Port backtype.storm.util to java
> --------------------------------
>
> Key: STORM-1226
> URL: https://issues.apache.org/jira/browse/STORM-1226
> Project: Apache Storm
> Issue Type: New Feature
> Components: storm-core
> Reporter: Robert Joseph Evans
> Assignee: Reza Farivar
> Labels: java-migration, jstorm-merger
>
> Port backtype.storm.util from clojure to java. In as many instances as
> possible the same interface should be maintained, and calls to clojure
> functions in the rest of the code should be replaces with calls to the
> corresponding java code.
> Some similar functions can be found at
> https://github.com/apache/storm/blob/jstorm-import/jstorm-core/src/main/java/com/alibaba/jstorm/utils/JStormUtils.java
> Although they are not identical.
> For function callbacks we may need to evaluate adding in appropriate callback
> interfaces instead. Please try to avoid using clojure internal java classes
> unless necessary.
