Subject Problems running GridMix2
Date Tue, 30 Nov 2010 16:05:11 GMT
Hi,

1 - I'm trying to run GridMix2 (rungridmix_2) in a cluster, but it happens  
nothing. A Job isn't created. It simple appears the message:

[code]
GridMix results:
Total num of Jobs: 0
ExecutionTime: 0
[/code]

Is there a way to know what is happenning with gridmix?


Here's the gridmix-env-2 config file:
[code]
#!/usr/bin/env bash

## Environment configuration
# Hadoop installation
export HADOOP_VERSION=hadoop-0.20.1
HADOOP_INSTALL_HOME=/opt
export HADOOP_HOME=${HADOOP_INSTALL_HOME}/hadoop
#export HADOOP_CONF_DIR=${HADOOP_HOME}/src/test/hadoop-site.xml (I also  
tried with this option)
#export HADOOP_CONF_DIR=${HADOOP_HOME}/conf/mapred-site.xml (I also tried  
with this option)
#export USE_REAL_DATASET=TRUE

export APP_JAR=${HADOOP_HOME}/${HADOOP_VERSION}-test.jar
export EXAMPLE_JAR=${HADOOP_HOME}/hadoop-0.20.2-dev-examples.jar
export  
STREAMING_JAR=${HADOOP_HOME}/contrib/streaming/${HADOOP_VERSION}-streaming.jar

[code]

2 - Running this example in my local machine, sometimes it runs, sometimes  
it don't. When the GridMix2 runs, I never saw it ending, but maybe because  
it's too many jobs to execute on my poor little PC. :( Am I right with this  
deduction?



Thanks,
Pedro
