Hello everyone=2C

I am having some trouble understanding the shortest path ex= ample=2C and some basic things of Giraph :

I am currently using the giraph-0.1-with-dependencies jar= =2C compiled from Maven=2C and Hadoop 0.20.203.0

When I launch the example=2C with the exact same input as g= iven in the example=2C with 1 worker=2C here is what I have as a result :

[0=2C0=2C[[1=2C0]]]

[1=2C0=2C[[2=2C100]]]

[2=2C100=2C[[3=2C200]]]

[3=2C300=2C[[4=2C300]]]

[4=2C600=2C[[5=2C400]]]

[5=2C1000=2C[[6=2C500]]]

[6=2C1500=2C[[7=2C600]]]

[7=2C2100=2C[[8=2C700]]]

[8=2C2800=2C[[9=2C800]]]

[9=2C3600=2C[[10=2C900]]]

[10=2C4500=2C[[11=2C1000]]]

[11=2C5500=2C[[12=2C1100]]]

[12=2C6600=2C[[13=2C1200]]]

[13=2C7800=2C[[14=2C1300]]]

[14=2C9100=2C[[0=2C1400]]]

If I choose a source ID of=2C for example=2C 3=2C I get (st= ill with one worker) :

[0=2C10200=2C[[1=2C0]]]

[1=2C10200=2C[[2=2C100]]]

[2=2C10300=2C[[3=2C200]]]

[3=2C0=2C[[4=2C300]]]

[4=2C300=2C[[5=2C400]]]

[5=2C700=2C[[6=2C500]]]

[6=2C1200=2C[[7=2C600]]]

[7=2C1800=2C[[8=2C700]]]

[8=2C2500=2C[[9=2C800]]]

[9=2C3300=2C[[10=2C900]]]

[10=2C4200=2C[[11=2C1000]]]

[11=2C5200=2C[[12=2C1100]]]

[12=2C6300=2C[[13=2C1200]]]

[13=2C7500=2C[[14=2C1300]]]

[14=2C8800=2C[[0=2C1400]]]

I see here that the node 3 has a 0 value on it=2C and thus = I understand that its the starting point. So everything is fine. =3B

I tried to add more edg= es and do the following graph :

[1=2C10=2C[[2=2C100]]]

[2=2C10=2C[[3=2C100]=2C[1=2C100]]]

[3=2C10=2C[[2=2C100]]]

I tried to start the job from node 2=2C but I didnt get any= output=2C my job gets stuck=85what am I doing wrong? I feel like when I ad= d edges=2C it always gets stuck.

Is there a problem in t= he way I add jobs? Or in my graph?

Also I was wondering how to add my own examples : what shou= ld I do if I want to add an example class? =3B

Can I do something like that :

hadoop jar giraph-0.1-jar-with-dependencies.jar myexamplecl= ass <=3Bargs>=3B

And if I do so=2C where should I place my myexampleclass cl= ass? =3B

Another newbie ques= tion : =3B

The shortestpaths example has a main meth= od=2C but some others don't. I understood that I need to use the GiraphRunn= er jar=2C but I don't really know how to use it : two arguments are needed = : the number of workers=2C and the input format=2C then the other arguments= .

Can someone tell me how I should do=2C for example=2C = to run the Shortestpaths example=2C with the 0.2 version of Giraph (this ve= rsion does not have a main method)?

Last question=2C why can't I use the bin/giraph command? (a= nd what is this command made for? Is it for running a giraph job jar? or ju= st to run the giraph jar?) whatever I do=2C it says "can't find the giraph = jar"=85.

Thanks a lot! I hope my questions were not too silly...

I hope I was clear enough=2C forgive my english=2C I am Fre= nch :)
