Hudson commented on HADOOP-6577:
--------------------------------

Integrated in Hadoop-Common-trunk-Commit #178 (See 
[http://hudson.zones.apache.org/hudson/job/Hadoop-Common-trunk-Commit/178/])
    . Add hidden configuration option "ipc.server.max.response.size" to change 
the default 1 MB, the maximum size when large IPC handler response buffer is 
reset. Contributed by Suresh Srinivas.


> IPC server response buffer reset threshold should be configurable

> In HDFS-6460, the response buffers in o.a.h.ipc.Server.Handler was reset when 
> the buffer grows beyond max size of 1MB. This frees heap from large responses 
> occupying it. This max response size limit should be configurable. Details in 
> subsequent comment.
