> Hi
> I was testing and found out that value assigned in the scheduler configuration is not consistent with what ResourceManager is assigning.
> If i set the configuration as below and understand that it is java float, but the rounding is not correct.
> capacity-sheduler.xml
> <property>
>   <name>yarn.scheduler.capacity.q1.capacity</name>
>   <value>7.142857142857143</value>
> </property>
> In Java:  System.err.println((7.142857142857143f)) ===> 7.142587 
> But, instead Resource Manager is assigning is 7.1428566
> Tested this on hadoop 2.7.2
