@ -315,6 +315,54 @@ The SYNTH mode of SLS is very convenient to generate very large loads without th
files. This allows to easily explore wide range of use cases (e.g., imagine simulating 100k jobs, and in different
runs simply tune the average number of mappers, or average task duration), in an efficient and compact way.
Resource Type in SLS
------------------------
This section talks about how to use resource type in SLS.
## Configure Resource Manager
This is the same to how to configure resource type for a real cluster. Configure
item `yarn.resource-types` in yarn-site.xml as the following example does.
<property>
<name>yarn.resource-types</name>
<value>resource-type1, resource-type2</value>
</property>
## Configure Node Manager
Specify the size of resource in each node by adding relevant items into
sls-runner.xml like the following example does. The values apply for every node
in SLS. The default values for resources other than memory and vcores are 0.
<property>
<name>yarn.sls.nm.resource-type1</name>
<value>10</value>
</property>
<property>
<name>yarn.sls.nm.resource-type2</name>
<value>10</value>
</property>
## Specify Resource in SLS JSON input
Resource Type is supported in SLS JSON input format, but not in other two
formats(SYNTH and RUMEN). To make it work in SLS JSON input format, you can
specify resource sizes for both task containers and the AM container. Here is an
example.
{
"job.start.ms" : 0,
"am.memory-mb": 2048,
"am.vcores": 2,
"am.resource-type1": 2,
"am.resource-type2": 2,
"job.tasks" : [ {
"container.duration.ms": 5000
"container.memory-mb": 1024,
"container.vcores": 1,
"container.resource-type1": 1,
"container.resource-type2": 1
}
}
