Setting Locality Groups via the API throws an exception
-------------------------------------------------------

                 Key: ACCUMULO-225
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-225
             Project: Accumulo
          Issue Type: Improvement
          Components: client, docs
    Affects Versions: 1.3.5
            Reporter: Jared Winick
            Assignee: Billie Rinaldi
            Priority: Minor


If a client attempts to set locality groups via the API and the client does not 
have core-site.xml on its classpath, the following exception is thrown after 
the groups are actually successfully set.

Exception in thread "main" 
org.apache.accumulo.core.client.impl.HdfsZooInstance$AccumuloNotInitializedException:
 Accumulo not initialized, there is no instance id at /accumulo/instance_id

The exception is confusing because:
1) the group(s) are actually created successfully
2) the exception misleads the user to believe there is something wrong with 
Accumulo's configuration where the problem is that the client isn't actually 
connecting to HDFS properly because it is missing core-site.xml on its 
classpath.
