Are you running on the sandbox (if so, what version ?) or your own cluster ?
In either case, please check the following configuration item in
capacity-scheduler.xml:
<property>
<name>yarn.scheduler.capacity.maximum-am-resource-percent</name>
<value>0.1</value>
<description>
Maximum percent of resources in the cluster which can be used to run
application masters i.e. controls number of concurrent running
applications.
</description>
</property>
Try increasing the value from 0.1 to 0.5, restart YARN and try launching
multiple applications again.
