Just to give an as complete view of my situation I am compiling what I have
done and what my problem is, so maybe you have the most complete information.
What I have done is the following in two virtual machines, with 4 cores and 4gb
ram each.
Install Debian 7.8. Plain with no graphical interface.
apt-get install openjdk-7-jdk openjdk-7-jre git maven curl
git clone http://git-wip-us.apache.org/repos/asf/samza.git
gradlew clean build
As there was a bug in the Keyrocks testing script I just commented the code in
the TestTTL script.

I have copied in the /opt/jobs/bin all the scrips in the

I have generated an eclipse project with the samza dependencies included, via
Maven, and no jobs, package it and copy to /opt/jobs/lib.
I have generated an eclipse project with the samza dependencies included, via
Maven, and three jobs that implement StreamTask and initiableTask. The
functions are empty, for testing purposes. It is published in a folder
published through apache web server.
I have created the associated job options file in the /opt/job/dtan folder like
this:

What I see:
• If I launch the three jobs, Only one of them gets to running
state. The one called Router. I it is always the same one. The others stay in
Accepted until they are killed by the system. I have seen these error:
o Container

beyond virtual memory limits. Current usage: 13.9 MB of 256 MB physical memory
used; 1.1 GB of 537.6 MB virtual memory used. Killing container
• When I kill the jobs with the kill-yarn-job.sh script the java
process does not get killed.
• Although I have set in the options that the job should be
launched with -Xms128M -Xmx128M I see that it runs with -Xmx768M. I have even
changed the run-class.sh script but it does not change.
Some things that I am describing do not make sense for me, so I am lost on what
to do or where to look.
Thanks for your help,
Jordi

I just changed the task options file to add the following line:
task.opts=-Xmx128M
And I found no change on the behaivour. I see that the job is being launched
with the default -Xmx768M value:

How do I set the correct value?

Hi, Jordi,
Please find the config variable task.opts in this table:
http://samza.apache.org/learn/documentation/0.9/jobs/configuration-table.html
This allows you to add additional JVM opts when launching the containers.
