      Description

      We found that Giraph jobs were consistently hanging if uppercase letters were included in the DNS (or /etc/hosts) resolved hostnames (foo.stanford.edu vs. foo.Stanford.EDU from our DNS). Normalizing the hostnames to lower case from GiraphConfiguration#getLocalHostname() fixed our problem.
