Subject Re: connected components example in giraph 1.0
Date Wed, 09 Oct 2013 07:47:16 GMT
*- you've successfully built it against a Hadoop 2.0.x release? *
no i've successfully built giraph 1.0 with cdh4.3 distribution, which have
inside YARN then MR2, but also MR1 hive pig impala hue etc ....
I suggest you use MR1 not MR2 ( that is YARN, tell me it's not stable)
Right to point out i use CDH Cloudera distribution because i took courses
with Cloudera and it's more easy to install for a non-System-Administrator
like me, there are many other Distributions.

*then use -Dhadoop.version=2.0.5 to build? *
i have used :
mvn clean install -P hadoop_cdh4.1.2
i don't believe exist "-D" option for Maven, should be "-P", -D it is used
for hadoop command line parameters.
However the fulcrum is the "pom.xml" file of giraph, inside this you can
see all the build possibility.

You can report this the error, you may have to wrong input format out put
format and so on:
how is your graph rapresentation? adjacency list?
care to the isolated vertex, Marco told me that the vertex only in the
neighbors list can cause problem, ex:
<source>\t<node1\tnode2\t ....>
1 2 3
2 4 1
....
in the adjacency list, 3 and 4 are prensent only like neighbors [2,3] and
[4,1], i believe you must replicate
1 2 3
1 4 1
*3*
*4*
the guy (giraph) is very susceptible.
