Hi Jason,

Thank you for your answer.

As of now I proceed by building Giraph with yarn profile. Next time when I launch EMR will
try with your suggestion.

Hi Nishant,

Try adding this either to your mapred-site.xml or your job properties:

# Let the YARN Resource Manager handle the MR2 job (any value other than local will do)

I am running my job on EMR. One solution I found is that I need to build giraph from source
code with hadoop_yarn profile.

Currently I add Giraph as maven dependency and it work without any issue. Is there any easy
way to handle this situation?

I am getting below error.

Exception in thread "main" java.lang.IllegalArgumentException: checkLocalJobRunnerConfiguration:
When using LocalJobRunner, must have only one worker since only 1 task at a time
