longer used.
12/06/06 21:09:12 WARN conf.Configuration: mapred.used.genericoptionsparser is
deprecated. Instead, use mapreduce.client.genericoptionsparser.used

Invalid usage.
with fix it outputs gridmix usage:

./hadoop-0.23.3-SNAPSHOT/share/hadoop/tools/lib/hadoop-gridmix-0.23.3-SNAPSHOT.jar
Generic options supported are
-conf <configuration file> specify an application configuration file
-D <property=value> use value for given property
-fs <local|namenode:port> specify a namenode
-jt <local|jobtracker:port> specify a job tracker
-files <comma separated list of files> specify comma separated files to be
copied to the map reduce cluster
-libjars <comma separated list of jars> specify comma separated jar files to
include in the classpath.
-archives <comma separated list of archives> specify comma separated
archives to be unarchived on the compute machines.
The general command line syntax is
bin/hadoop command [genericOptions] [commandOptions]

<trace>
e.g. gridmix -generate 100m foo -
Options:

generate
distributed cache data under <iopath>/distributedCache/.
-users <usersResourceURI> : URI that contains the users list.
