Label with given name does not exist Exception

[Sotiris Beis]

Hi, 

I have the following code: 

public class TitanMassiveInsertion {

private TitanGraph titanGraph = null;

private BatchGraph<TitanGraph> batchGraph = null;

public static void main(String args[]) {

TitanMassiveInsertion test = new TitanMassiveInsertion();

test.startup("data/titanDB");

test.createGraph("data/flickrEdges.txt");

test.shutdown();

}

public void startup(String titanDBDir) {

System.out.println("The Titan database is now starting . . . .");

BaseConfiguration config = new BaseConfiguration();

        Configuration storage = config.subset(GraphDatabaseConfiguration.STORAGE_NAMESPACE);

        storage.setProperty(GraphDatabaseConfiguration.STORAGE_BACKEND_KEY, "local");

        storage.setProperty(GraphDatabaseConfiguration.STORAGE_DIRECTORY_KEY, titanDBDir);

        storage.setProperty(GraphDatabaseConfiguration.STORAGE_BATCH_KEY, true);

titanGraph = TitanFactory.open(config);

titanGraph.createKeyIndex("nodeId", Vertex.class);

titanGraph.commit();

batchGraph = new BatchGraph<TitanGraph>(titanGraph, VertexIDType.STRING, 1000);

batchGraph.setVertexIdKey("nodeId");

batchGraph.setLoadingFromScratch(true);

}

public void createGraph(String datasetDir) {

System.out.println("Creating the Titan database . . . .");

try {

BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(datasetDir)));

String line;

int lineCounter = 1;

int nodeCounter = 0;

Vertex srcVertex, dstVertex;

while((line = reader.readLine()) != null) {

if(lineCounter > 4) {

String[] parts = line.split("\t");

srcVertex = batchGraph.getVertex(parts[0]);

if(srcVertex == null) {

srcVertex = batchGraph.addVertex(parts[0]);

srcVertex.setProperty("nodeId", parts[0]);

nodeCounter++;

}

dstVertex = batchGraph.getVertex(parts[1]);

if(dstVertex == null) {

dstVertex = batchGraph.addVertex(parts[1]);

dstVertex.setProperty("nodeId", parts[1]);

nodeCounter++;

}

Edge edge = batchGraph.addEdge(null, batchGraph.getVertex(parts[0]), batchGraph.getVertex(parts[1]), "similar");

System.out.println(edge);

System.out.println(nodeCounter);

}

lineCounter++;

}

reader.close();

}

catch(IOException ioe) {

ioe.printStackTrace();

}

}

public void shutdown() {

System.out.println("The Titan database is now shuting down . . . .");

if(titanGraph != null) {

batchGraph.shutdown();

titanGraph.shutdown();

batchGraph = null;

titanGraph = null;

}

}

}

I keep getting the following error:

I think you need to define your types up front when batchloading is turned on.  I don't see where you are defining your schema in your code sample:

https://github.com/thinkaurelius/titan/wiki/Type-Definition-Overview

Defining types up front is recommended practice with or without batchloading.

This is happening even when label is defined; Seems to be a bug. It is throwing error at the default label tag

mgmt.makeVertexLabel("ID").make()

val serving_cell: Vertex = GraphDBConnectionTest.graph.asScala.addVertex("cell")

or
val serving_cell: Vertex = GraphDBConnectionTest.graph +(s"cell-1", ID -> s"cell-2")

or

val serving_cell: Vertex = GraphDBConnectionTest.graph.addVertex(T.label,"cell")

java.lang.IllegalArgumentException: Vertex Label with given name does not exist: cell

Hi Alex,

You must have the schema.default=none in your Titan properties. When automatic schema creation is disabled like this, you must first define the label through the schema management system before attempting to create a vertex that uses it. Make sure you commit() the schema also.
