title: Storm missing resources folder when deploying JAR topology
body: <p>I'm trying to deploy a topology that uses a MultiLang Bolt (written in Python):</p>
  
  <pre><code>builder.setBolt("avro-parser", new AvroBolt(), 3).shuffleGrouping("main-kafka-spout");
  builder.setBolt("nlp-analyzer", new NLPBolt("/python/analyzer/audio_parser.py"), 2).shuffleGrouping("avro-parser");
  </code></pre>
  
  <p>I can submit the topology without problems, but checking the log files I see this error:</p>
  
  <pre><code>java.lang.RuntimeException: Error when launching multilang subprocess

  <p>Of course, I've noticed that I don't have a "resources" folder in the specified log trace:</p>
  
  <blockquote>
    <p>/var/lib/storm/supervisor/stormdist/sintonea-topology-main-22-1472285031/resources</p>
  </blockquote>
  
  <p>If you do a "ls" command in that directory, you'll see it:</p>
  
  <pre><code>stormcode.ser  stormconf.ser  stormjar.jar
  </code></pre>
  
  <p>Why storm is not creating a resources folder in that directory? </p>
  
  <p>I have two resources folders inside src/main/resources: </p>
  
  <ul>
  <li>schema: contains avro scheme files</li>
  <li>python: contains the python code</li>
  </ul>
  
  <p>These folders are copied into the JAR in the root directory, instead of a /resources folder.</p>
  
  <p>How is that possible? I have an AvroBolt that is using an schema in this way and it's not giving any problem (tested with a DummyBolt instead of MultiLang Bolt):</p>
  
  <pre><code>_schema = parser.parse(getClass().getResourceAsStream("/schema/caller_request.avsc"));
  </code></pre>
  
  <p><strong>EDIT</strong></p>
  
  <p>I've moved my resources folder to </p>
  
  <blockquote>
    <p>baseDirectory.value / "multilang"</p>
  </blockquote>
  
  <p>After reading this:</p>
  
  <p><a href="http://storm.apache.org/releases/current/Creating-a-new-Storm-project.html" rel="nofollow">http://storm.apache.org/releases/current/Creating-a-new-Storm-project.html</a></p>
  
  <p>Now the resource folder is created and copied, but I'm still having the same issue:</p>
  
  <pre><code>Serializer Exception:
  /usr/bin/python: can't open file '/resources/python/analyzer/audio_parser.py': [Errno 2] No such file or directory
  </code></pre>
  
  <p><strong>EDIT 2</strong></p>
  
  <p>I've found a workaround (create two resources folders at different levels): </p>
  
  <ol>
  <li>Create a multilang/resources in the parent directory of src (one level up). Copy the python folder inside: {base-directory}/multilang/resources/python/*.py</li>
  <li>Leave intact the folder src/main/schema: {base-directory}/src/main/resources/schema/caller_request.avsc.</li>
  </ol>
  
  <p>And added this to my build.sbt:</p>
  
  <pre><code>unmanagedResourceDirectories in Compile += { baseDirectory.value / "multilang" }
  unmanagedClasspath in Compile += baseDirectory.value / "multilang"
  </code></pre>
  
  <p>And set up my ShellBot as (ignoring the word "resources" or "/" in path):</p>
  
  <pre><code>NLPBolt nlpBolt = new NLPBolt("python/analyzer/audio_parser.py");
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>_schema = parser.parse(getClass().getResourceAsStream("/schema/caller_request.avsc"));
  </code></pre>
  
  <p>It seems to work, but I don't like this solution. Any thoughts?</p>
  
  <p><strong>EDIT 3</strong></p>
  
  <p>By the way, this code:</p>
  
  <pre><code>import storm
  #from nltk.stem.snowball import SnowballStemmer
  from es_tagger import SpanishTagger
  
  config = utils.load_json('python/analyzer/data/config.json')
  
  class AudioParserBolt(storm.BasicBolt):
  </code></pre>
  
  <p>Produces the following error:</p>
  
  <pre><code>Serializer Exception:
  Traceback (most recent call last):
    File "python/analyzer/audio_parser.py", line 27, in &lt;module&gt;
      class AudioParserBolt(storm.BasicBolt):
  AttributeError: 'module' object has no attribute 'BasicBolt'
  </code></pre>
