Hi Lukas,
Thank you so much for your reply. I have tried what you told.
I have opened pom.xml. I have seendifferent profile id(s) and by default
Hadoop-0.20.203 is true. I have changed by default activation property to
Hadoop-2.0.0 but build failed with -
[ERROR] The build could not read 1 proj
Perhaps you have not specified EdgeInputFormat and EdgeOutFormat in your
jar run command. And it is just a message not exception as you can see that
your task runs.

That's pretty interesting. Forgot to mention, the output I get is
--3--
--4--
--5--
--6--
--7--
So it does look like something is up with Java.

Hmm yea, the only difference between mine and your system is the hadoop
your using and maybe the jdk. I think it's most likely something to do with
the jdk in this respect.

it's because of the space between the \t and closing ] in [\t ]. This will
separate output by a space. Whereas if you just have [\t] it will separate
this out using tab spacing.

Ah yeah, I found the answer to that question:
https://stackoverflow.com/questions/3762347/
So I don't think that bit is a bug. I'm not really sure why inputs with
tabs don't work for you. I'm using Hadoop 1.0.4 and jdk1.6.0_30 on Ubuntu
12.04 x64, if that helps you.

Hey,
Yes when originally debugging the code I thought to check what \t actually
split by and created my own test class:
import java.util.regex.Pattern;
class App
{
private static final Pattern SEPARATOR = Pattern.compile("[\t ]");
public static void main( String[] args )
{
String
Weird, inputs with tabs work for me right out of the box. Either the "\t"
is not the cause or it's some Java-version specific issue. Try this toy
program:
import java.util.regex.Pattern;
public class Test {
public static void main(String[] args) {
Pattern SEPARATOR = Pattern.compile("[\t ]
Huh, it might be a bug in the code. Could it be that Pattern.compile has to
take "[\\t ]" (note the double backslash) to properly match tabs? If so,
that bug is in all the input formats...
Happy to help :)

Hi,
I removed the spaces and it worked! I don't understand though. I'm sure the
separator pattern means that it splits it by tab spaces?.
Thanks for all your help though some what relieved now!
Kind regards,

Hi,
That looks like an error with the algorithm... What do the Hadoop userlogs
say?
And just to rule out weirdness, what happens if you use spaces instead of
tabs (for your input graph)?

Hey,
No even after I added the .txt it gets to map 100% then drops back down to
50 and gives me the error:

Hmm.. it looks like a failure during graph loading. Did you forget a .txt
in the input path?

Hi,
Thanks for the speedy response!
It didn't work for me :(.
I updated the ConnectComponentsVertex class with yours and added in the new
ConnectedComponentsInputFormat class. They are both in the
giraph-examples/src/main/java/org/apache/giraph/examples package.

Why this kind of error comes? What could be wrong? Is it related with

Hey,
Sure, I've uploaded the 1.0.0 classes I'm using:

They both go into giraph-examples/src/main/java/org/apache/giraph/examples

Hi Young,
I'd just like to say first thank you for your help it's much appreciated!
I did the sanity check and everything seems fine I see the correct results.
Yes I hadn't noticed that before that is strange, I don't know how that
happened as on the quick start guide (

Hi Pascal,
I was able to install Hadoop 2.0.0 with CDH 4.6 repository. But now I need
to build Giraph jar file for Hadoop 2.0.0.mI did "maven compile" but it
gave me giraph-1.0.0-for-hadoop-0.20.203.0-jar-with-dependencies.jar.
I need giraph-1.0.0-for-hadoop-2.0.0-jar-with-dependencies.jar.
Pleas
Open pom.xml file from giraph-parent project, choose corresponding maven
profile, active it from command line and recompile Giraph.
