Thanks for all. Thanks for [~rkanter],[~djp]. I will try the HadoopArchiveLogs.

By the way I see that YARN-431 Stabilize YARN application log-handling. But None of them basically
solve the containers increase  making too many small files and causing a problem for the NN
at once. 

 If we don't enable  log aggregation and can provide "yarn logs" to get logs.  The problem
will gone forever.  
The thing I face is that we can't get the app and contianerReport  relationship  when the
app finish(Spark).

> Nowdays We have large cluster,with the apps incr and container incr ,We split an  namespace
to store applogs. 
> But the  log-aggregation /tmp/app-logs incr also make the namespace responce slow.  
> We want to chang yarn.log-aggregation-enable true -> false,But Transform the the yarn
log cli service also can get the app-logs.
