Luke Lu commented on MAPREDUCE-3936:
------------------------------------

bq. the generic history server can display the counters with existing behavior 
(preserving system counters while displaying an error showing that user counter 
limits have been exceeded)

Sorry, this is not possible as the generic history server has no internal 
knowledge of MR counters. It can use a pageable/scroll-on-demand widget to 
display arbitrarily large json object though.
                
> Clients should not enforce counter limits

> The code for enforcing counter limits (from MAPREDUCE-1943) creates a static 
> JobConf instance to load the limits, which may throw an exception if the 
> client limit is set to be lower than the limit on the cluster (perhaps 
> because the cluster limit was raised from the default).
