--------------------------------------

             Summary: SolrJ: CloudSolrServer atomic updates doesn´t work with Lists/Arrays
(Objects, in general).
                 Key: SOLR-4080
                 URL: https://issues.apache.org/jira/browse/SOLR-4080
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
    Affects Versions: 4.0
         Environment: Solr 4.0 with SolrCloud deployed with two SolrServers with shards=1.
solr-solrj artifact version 4.0.0 is used to execute atomic update operations.
            Reporter: Luis Cappa Banda


Atomic updates with a CloudServer object instance doesn´t work properly. 

- Code snippet:

// CloudSolrSever instance.
LBHttpSolrServer lbSolrServer = new LBHttpSolrServer(solrEndpoints);
CloudSolrServer cloudSolrServer = new CloudSolrServer(zookeeperEndpoints, lbSolrServer);

// SolrInputDocument to update: 
SolrInputDocument do = ne SolrInputDocument();
doc.addField("id", "myId");

Map<String, List<String>> operation = new HashMap<String, List<String>>();
operation.put("set", [[a list of String elements]]);  // I want a set operation to override
field values.
doc.addField("fieldName", operation);

// Atomic update operation.
cloudSolrServer.add(doc); 


- Result:

doc: {
    id: "myId",
    fieldName: [ "{set=values}"
    ],

    ...
}

- Changing map from snippet like Map operation = new HashMap() instead of Map<String, List<String>>
operation = new HashMap<String, List<String>>() obtains the following result after
the atomic update:

doc: {
    id: "myId",
    fieldName: ["[Value1, Value2]"
    ],

    ...
}

- Also, the old value is never erased, and instead of a "set" operation an "add" operation
happens.


CONCLUSION: during an atomic update with CloudSolrServer the List/Array/Object value passed
is being processed with just a toString() method.
