- * This is a map reduce test for testing hcat which goes against the "numbers"
- * table. It performs a group by on the first column and a SUM operation on the
- * other columns. This is to simulate a typical operation in a map reduce
- * program to test that hcat hands the right data to the map reduce program
- *
- * Usage: hadoop jar sumnumbers <serveruri> <output dir> <-libjars hive-hcat
- * jar> The <tab|ctrla> argument controls the output delimiter The hcat jar
- * location should be specified as file://<full path to jar>
