Maja Kabiljo commented on GIRAPH-529: ------------------------------------- That example on the github was written very long time ago, and API changed a lot since then. There is no getOutEdgeMap() method anymore, you should call vertex.getEdges() to get edge iterator. You can also take a look at SimpleShortestPathsVertex in the giraph-examples. > Compile error when compiling the giraph shortest path problem: getOutEdgeMap() > ------------------------------------------------------------------------------ > > Key: GIRAPH-529 > URL: https://issues.apache.org/jira/browse/GIRAPH-529 > Project: Giraph > Issue Type: Bug > Environment: Fedora 18(64-bit), hadoop-1.0.4 version, giraph-0.1.0 > version > Reporter: eunjihwang > > I have some problem when I compiling the giraph shortest path problem > I can't understand exactly getOutEdgeMap() method. > Should I implement it? > and also I have other compile errors. > I just write a source code like this; > https://github.com/aching/Giraph/wiki/Shortest-Paths-Example > I attach error messages. > -------------------- > sp/SimpleShortestPathVertex.java:55: error: cannot find symbol > for(Edge<LongWritable, FloatWritable> edge : getOutEdgeMap().values()){ > ^ > symbol: method getOutEdgeMap() > location: class SimpleShortestPathVertex > sp/SimpleShortestPathVertex.java:74: error: cannot find symbol > FileInputFormat.addInputPath(job, new Path(args[0])); > ^ > symbol: variable FileInputFormat > location: class SimpleShortestPathVertex > sp/SimpleShortestPathVertex.java:75: error: cannot find symbol > FileOutputFormat.setOutputPath(job, new Path(args[1])); > ^ > symbol: variable FileOutputFormat > location: class SimpleShortestPathVertex > sp/SimpleShortestPathVertex.java:88: error: no suitable method found for > run(SimpleShortestPathVertex,String[]) > System.exit(ToolRunner.run(new SimpleShortestPathVertex(), args)); > ^ > method ToolRunner.run(Tool,String[]) is not applicable > (actual argument SimpleShortestPathVertex cannot be converted to Tool > by method invocation conversion) > method ToolRunner.run(Configuration,Tool,String[]) is not applicable > (actual and formal argument lists differ in length) > sp/SimpleShortestPathVertex.java:100: error: SimpleShortestPathVertexReader > is not abstract and does not override abstract method getCurrentVertex() in > VertexReader > class SimpleShortestPathVertexReader extends TextVertexReader<LongWritable, > DoubleWritable, FloatWritable, DoubleWritable>{ > ^ > sp/SimpleShortestPathVertex.java:121: error: method addEdge in class > MutableVertex<I,V,E,M> cannot be applied to given types; > vertex.addEdge(new Edge<LongWritable, FloatWritable>(new > LongWritable(jEdge.getLong(0)), new > FloatWritable((float)jEdge.getDouble(1)))); > ^ > required: LongWritable,FloatWritable > found: Edge<LongWritable,FloatWritable> > reason: actual and formal argument lists differ in length > where I,V,E,M are type-variables: > I extends WritableComparable declared in class MutableVertex > V extends Writable declared in class MutableVertex > E extends Writable declared in class MutableVertex > M extends Writable declared in class MutableVertex > sp/SimpleShortestPathVertex.java:139: error: lineRecordWriter has private > access in TextVertexWriter > super(lineRecordWriter); > ^ > sp/SimpleShortestPathVertex.java:150: error: cannot find symbol > for(Edge<LongWritable, FloatWritable> edge : > vertex.getOutEdgeMap().values()){ > ^ > symbol: method getOutEdgeMap() > location: variable vertex of type > BasicVertex<LongWritable,DoubleWritable,FloatWritable,?> > 8 errors -- This message is automatically generated by JIRA.
