Subject [jira] [Commented] (HADOOP-12866) add a subcommand for gridmix
Date Thu, 05 May 2016 21:38:13 GMT

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}
