I believe the argument order listed in these examples is incorrect, but please verify. The zookeeper quorum should be after the other arguments, like this:

                "  psql -t my_table my_cluster:1825 my_table2012-Q3.csv\n" +
                "  psql -t my_table -h col1,col2,col3 my_cluster my_table2012-Q3.csv\n" +
                "  psql -t my_table -h col1,col2,col3 -d 1 2 3 my_cluster my_table2012-Q3.csv\n"
