> When users called ApplicationClientProtocol.getApplications, it will return 
> lots of data, and generate lots of garbage on ResourceManager which caused 
> long time GC.
> For example, on one of our RM, when called rest API " http://<rm http 
> address:port>/ws/v1/cluster/apps" it can return 150MB data which have 944 
> applications.
> getApplications have limit parameter, but some user might not set it, and 
> then the limit will be Long.MAX_VALUE.
