Harsh J commented on HADOOP-8055:
---------------------------------
Eric - The absence of a core-site.xml means the core-default.xml alone is
loaded, and it has an fs.defaultFS in it set to file:/// OOB.
However, I agree our log messages, and our guards can be even better. Could you
file another JIRA with your suggestions? I'll be happy discuss and carry it
over from there :)

> A dist built from trunk (0.24.0-SNAPSHOT) does not contain a core-site.xml in
