Allen Wittenauer commented on HADOOP-12866:
-------------------------------------------
OK, looks like it is.
But the documentation fix is slightly incomplete. This whole section should
just get removed since hadoop gridmix takes care of it all:
{code}
GridMix expects certain library *JARs* to be present in the *CLASSPATH*.
One simple way to run GridMix is to use `hadoop jar` command to run it.
You also need to add the JAR of Rumen to classpath for both of client and tasks
as example shown below.
```
HADOOP_CLASSPATH=$HADOOP_HOME/share/hadoop/tools/lib/hadoop-rumen-2.5.1.jar \
$HADOOP_HOME/bin/hadoop jar
$HADOOP_HOME/share/hadoop/tools/lib/hadoop-gridmix-2.5.1.jar \
-libjars $HADOOP_HOME/share/hadoop/tools/lib/hadoop-rumen-2.5.1.jar \
[-generate <size>] [-users <users-list>] <iopath> <trace>
```
{code}
> add a subcommand for gridmix
