rahul k singh commented on MAPREDUCE-1009:
------------------------------------------

cluster_setup.xml

1. In the section conf/mapred-queues.xml . 
When we are explaninig the properties we need to specify whether we can change the value using refresh or not
So we can have 3rd column 
can be refreshed.
values being yes , no and Not applicable.
2. Instead of "both from the command line (See this and this)"  instead of this , we can use -list and -info.
3. In section "Refreshing queue configuration" we should mention that no change is allowed to hierarchy of queues. either in terms of structure or in terms of name. Only properties are allowed to change.
Instead we are just saying "Not all configuration properties can be reloaded of course. For example, new queues cannot be added dynamically, neither can an existing queue be deleted"

capacity_scheduler.xml
1. In section "Configuring Properties for Queues" the table should have seperate column for refresh as mentioned for cluster_setup.xml
