The JobTracker should ensure that it is running on the right host.

Key: HADOOP-1819
URL: https://issues.apache.org/jira/browse/HADOOP-1819
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.14.0
Reporter: Owen O'Malley
Assignee: Owen O'Malley
Fix For: 0.15.0
We had someone start up a private JobTracker with the standard config.
Unfortunately, it used the system directory from the config and wiped it clean.
I want to add a sanity check that makes sure the JobTracker is being run on the
right node before the system directory is wiped.
