That your drivers have exceeded max memory configured in Max Application Master Resources. You can either increase max memory for AM or decrease driver memory in your jobs.
- 解决方案1：调整yarn.scheduler.capacity.maximum-am-resource-percent
<property>
<!-- Maximum resources to allocate to application masters
If this is too high application masters can crowd out actual work -->
<name>yarn.scheduler.capacity.maximum-am-resource-percent</name>
<value>0.6</value>
</property>
- 解决方案2：decrease driver memory in your jobs.
