Hong Zhiguo commented on YARN-1545:
-----------------------------------
You mean we should define the upper bound of the number or length of fields
inside the messages. Should we have these bounds configurable? or pre-defined
as constants?
How about the rate of messages? For example, a bad client performs query of
getApplications at it's full speed.
