Luke Lu commented on HADOOP-9151:
---------------------------------
Binglin's point 3 actually brings up a serious security issue with the current
RPC protocol/implementation: it's trivial for any (low-bandwidth) client to DoS
any Hadoop RPC service (with unlimited-bandwidth). The fact the current
protocol is not amenable to nonblocking reader is a serious issue that needs to
be fixed ASAP.
I proposed a simple fix in HADOOP-9194.
> Include RPC error info in RpcResponseHeader instead of sending it separately
