Failed to re-init queues : Illegal queue capacity setting (abs-capacity=0.6) ＞ (abs-maximum-capacity

今天在给Yarn分配队列的时候抛出了如下异常，

原因：默认的额定队列容量大于最大上线队列容量
解决方案：

<!-- 降低default队列资源额定容量为40%，默认100% -->
<property>
    <name>yarn.scheduler.capacity.root.default.capacity</name>
    <value>40</value>
</property>

<!-- 降低default队列资源最大容量为60%，默认100% -->
<property>
    <name>yarn.scheduler.capacity.root.default.maximum-capacity</name>
    <value>60</value>
</property>
