Subject [jira] [Commented] (HADOOP-9151) Include RPC error info in RpcResponseHeader instead of sending it separately
Date Mon, 14 Jan 2013 12:52:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13552623#comment-13552623
] 

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.
