>
> Currently, capacity scheduler doesn't trim sub queue name when parsing queue
> names, for example, the configuration
> {code}
> <configuration>
> <property>
> <name>...root.queues</name>
> <value> a, b , c</value>
> </property>
> <property>
> <name>...root.b.capacity</name>
> <value>100</value>
> </property>
>
> .......
> </property>
> {code}
> Will fail with error:
> {code}
> java.lang.IllegalArgumentException: Illegal capacity of -1.0 for queue root.

> at
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue.getCapacityFromConf(LeafQueue.java:196)
> ....
> {code}
> It will try to find a queues with name " a", " b ", and " c", which is
> apparently wrong, we should do trimming on these sub queue names.
