[jira] [Created] (STORM-2327) Abstract class ConfigurableTopology

Julien Nioche created STORM-2327:
------------------------------------

             Summary: Abstract class ConfigurableTopology
                 Key: STORM-2327
                 URL: https://issues.apache.org/jira/browse/STORM-2327
             Project: Apache Storm
          Issue Type: New Feature
          Components: storm-core
    Affects Versions: 2.0.0
            Reporter: Julien Nioche
            Priority: Minor


Classes which run topologies often repeat the same code and pattern to:
* populate the configuration from a file instead of ~/.storm
* determine whether to run locally or remotely
* set a TTL for a topology

Flux provides an elegant way of dealing with these but sometimes it is simpler to define a topology in Java code. 

In [StormCrawler|http://stormcrawler.net], we implemented an abstract class named ConfigurableTopology which can be extended and saves users the hassle of having to write code for the things above. I will open a PR containing this class so that we can discuss and comment whether it is of any use at all.
