Hi, I have the following configuration in yarn-site.xml,
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.scheduler.minimum-allocation-mb</name>
<value>256</value>
</property>
<property>
<name>yarn.scheduler.maximum-allocation-mb</name>
<value>512</value>
</property>
<property>
<name>yarn.nodemanager.resource.memory-mb</name>
<value>1536</value>
</property>
and in mapred-site.xml I have
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<property>
<name>yarn.app.mapreduce.am.resource.mb</name>
<value>512</value>
</property>
<property>
<name>yarn.app.mapreduce.am.command-opts</name>
<value>-Xmx384m</value>
</property>
But, when I am starting a resource manager I am getting the following error
2015-05-03 16:37:09,370 WARN
org.apache.hadoop.yarn.server.resourcemanager.RMAppManager: RM app submission
failed in validating AM resource request for application
application_1422432138055_0002
org.apache.hadoop.yarn.exceptions.InvalidResourceRequestException: Invalid
resource request, requested memory < 0, or requested memory > max configured,
requestedMemory=1536, maxMemory=512
By making some tests I determined that ‘maxMemory’ is related to
'yarn.scheduler.maximum-allocation-mb’
But what is requestedMemory=1536? I find some info on the internet, and it said
that it is memory for Application Master, but as you can see, I’ve configured
AM to use 512 mb in mapred-site.xml.
What is wrong here?
Thank you.

Akmal Abbasov
