> 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>

>          <value>100</value>
>      </property>
>       
>      .......
> </property>
> {code}
> Will fail with error: 
> {code}
> java.lang.IllegalArgumentException: Illegal capacity of -1.0 for queue root. a 
> 	at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerConfiguration.getCapacity(CapacitySchedulerConfiguration.java:332)
> 	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.
