Hi,
I'm using Hadoop 2.0.3.alpha with a single node set-up, and Giraph 1.0.0.
When I try the PageRank example I get this error:
Exception in thread "main" java.lang.IllegalArgumentException:
checkLocalJobRunnerConfiguration: When using LocalJobRunner, must have only
one worker since only 1 task at a time!
at
org.apache.giraph.job.GiraphJob.checkLocalJobRunnerConfiguration(GiraphJob.java:151)
When I set the number of workers to 1, I get this:
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!
at
org.apache.giraph.job.GiraphJob.checkLocalJobRunnerConfiguration(GiraphJob.java:157)
I have found another message reporting about the same problem, but it was
not answered. Any help is highly appreciated.
Cheers,
Christian
