    Description

      On the local file system, we have a mount point /opt, inside /opt, we have symlink called "0" -> .
      HOD is installed in /opt/0/hod.
      All the directory values inside the hodrc file utilize the /opt/0/hod values.
      When trying to allocate the cluster, it gave the following result:

      $ hod allocate -d mycluster -n 5
      CRITICAL - No job found, ringmaster failed to run.
      CRITICAL - Cannot allocate cluster /homes/jim/mycluster

      No other additional error messages was produced.
      To fix this issue, the symlink 0 -> . was removed.
      An actual directory called 0 was created in its place and hod was put inside of it.
      After the cluster was able to be allocate.
