Hi,
I am working with Giraph 1.1.0 and a YARN cluster with Hadoop 2.6.0.
I build Giraph with
mvn -Phadoop_2 -Dhadoop.version=2.6.0 clean package -DskipTests
So far, when I run any of the benchmarks or Shortest path examples, I
always get the LocalJobRunner error :
---------------------------------------------------------------------------------------
Exception in thread "main" java.lang.IllegalArgumentException:
checkLocalJobRunnerConfiguration: When using LocalJobRunner, you cannot run
in split master / worker mode since there is only 1 task at a time!

-------------------------------------------------------------------
I have tried some solutions from forums/StackOverflow/lists, but so far
nothing has worked. As far as I can tell, Hadoop is configured right (other
MR benchmarks run fine). I tried changing the above Giraph code file
(making the check function returned what I wanted), but that only starts
the Job and gets it running on a single machine - it never uses more than 1
machine.
Any help or pointers in the right direction would be much appreciated.
Thanks,
Kenrick
