> URL: https://issues.apache.org/jira/browse/HADOOP-4059

> Hadoop has lots of tests that start clusters, but I don't see any that test
> the command line scripts working. Which means that changes to the scripts and
> the code behind them may not get picked up rapidly, and regressions won't get
> picked up by Hudson and apportioned to the specific patches.
> Propose:
> * an abstract test case that can exec scripts on startup; wait for them to
> finish, kill them if they take too long
> * test cases for every service (namenode, tasktracker, datanode, etc)
> * tests that try invalid commands, -help options
> * tests that start the services, assert that they are live, and shut them down
