Where are the job configurations?

[ikapoura]

Hello there!

  today I came back from a long vacation from programming with  
giraph. I compiled the latest version and I am so lost with the  
changes! So, can anybody help me with the following questions?

Q1: Where are all the job.set functions from GiraphJob? Like  
job.setVertexClass(), job.setVertexInputFormatClass() etc?

Q2: When I create a Reader which implements TextVertexReader<I,V,E>  
and I have the constructor
    public Reader (
            RecordReader<I,V> recordreader) {
        super(recordreader);
    }

   I have an error that it cant find the class TextVertexReader.

Q3: (if it isn't much pain to you) can you provide me a snipper of  
code for a TestVertex and a TestReader? Only the declarations! I don't  
care much about the type of the id,value and messages.

Thanks,
Ilias
