To resolve this issue, open /opt/cloudera/cm/bin/gen_credentials.sh for editing and add the following to the very end of the script:

exit ${PIPESTATUS[0]}

And then try generating Kerberos credentials once more. If it fails again, you should see much more detail assisting in troubleshooting.

This will be addressed in a future release of Cloudera Manager.
