Usually, it works well if you don’t classify capital and small letter, hostname in “/etc/hostname” and “/etc/hosts” in hadoop eco system.
But in Giraph if you don’t classify capital and small letter, it will stop without any Error and Debug message. Be sure to classify capital and small letter when you are setting hostname.
