Tests: NullPointerException parser.QueryParser.Alias(QueryParser.java:471)
--------------------------------------------------------------------------

                 Key: PIG-100
                 URL: https://issues.apache.org/jira/browse/PIG-100
             Project: Pig
          Issue Type: Bug
          Components: impl
    Affects Versions: 0.1.0
            Reporter: Benjamin Francisoud
            Priority: Minor


I think the root problem was that I forget to specify the configuration using -Djunit.hadoop.conf=hadoop-site.xml
while running the tests.
But the error could be clearer...

The logs are big so I will provide them in a separate file...

But the core problem is:
