Examples of org.apache.pig.pigunit.pig.GruntParser

org.apache.pig.pigunit.pig.GruntParser
Slightly modified GruntParser that accepts a list of aliases to override.
This is a way to replace a pig query by another query.
For example, if we have this map of overrides: Map<alias,query>
- <A, A=LOAD '/path'> --> replace the alias A by A = LOAD '/path'
- <DUMP, > --> remove the DUMP queries
It might be possible to do the same thing in a less hacky way. e.g. pig.registerQuery replace the query of a certain alias...

  public void setUp() {
    override = new HashMap<String, String>() {{
      put("STORE", "");
      put("DUMP", "");
    }};
    parser = new GruntParser(new StringReader(""), override);
  }
