This is a project to develop and build Hadoop (HDFS and MAPREDUCE) smoke and
system tests.

System property "tests" can be set to select individual tests from the
available MapReduce jobs. To set the property, include the following
option in the command line (with your chosen jobs): -Dtests="teragen,terasort"

The default number of terasort rows (1000) can be changed with the system
property "terasort_rows": -Dterasort_rows=50
