Subject Running scale tests
Date Mon, 29 Aug 2011 05:07:53 GMT

The following questions are from an system administrator point of view.

How do I run scale tests using different numbers of nodes ?  Do I have to
shutdown and restart hadoop to do this ?
What about dfs, do I have to reformat when changing the number of nodes down

Is there a "machines file" as done in MPI where I can specify just the
number of nodes to be used for a test ?
