Subject [jira] Commented: (HADOOP-4059) Add tests that try starting the various hadoop command line scripts
Date Wed, 03 Sep 2008 16:21:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4059?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12628039#action_12628039

Nigel Daley commented on HADOOP-4059:

FYI, I think org.apache.hadoop.cli.TestCLI tests some of this.

> 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
