Subject GridMix doesn't run ClassNotFoundException Rumen
Date Mon, 14 Dec 2015 09:56:46 GMT
Hello folks,

I am trying to run a simulation with GridMix but the simulation fails 
every time.

If I inspect the log I find the error with looks like this:

    "Error:
    *java.lang.ClassNotFoundException:
    org.apache.hadoop.tools.rumen.ResourceUsageMetrics\n\tat*

    org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:158)\n",

The error is pretty clear, but I have no idea how to fix it.

I run GridMix by command line with:

    bin/hadoop jar share/hadoop/tools/lib/hadoop-gridmix-2.6.1.jar
    iopath trace.json

Any hits ?

Cheers :)

Simone
