Xiaobing Zhou commented on HADOOP-12957:
----------------------------------------
I posted patch v000 for review. There could be two changes:
1. make asyncCallCounter as a thread local so it makes each thread being
subject to the threshold. But there might be a couple of caller threads doing
async calls, which exacerbates buffer usage.
2. make asyncCallCounter configurable.
I'd like to know reviewers' comments on these. Thanks.

> In async RPC, if the callers don't read replies fast enough, the buffer
> storing replies could be used up. This is to propose limiting the number of
> outstanding async calls to eliminate the issue.
