Colin Patrick McCabe created HADOOP-9676: --------------------------------------------
Summary: make maximum RPC buffer size configurable Key: HADOOP-9676 URL: https://issues.apache.org/jira/browse/HADOOP-9676 Project: Hadoop Common Issue Type: Improvement Reporter: Colin Patrick McCabe Assignee: Colin Patrick McCabe Priority: Minor Currently the RPC server just allocates however much memory the client asks for, without validating. It would be nice to make the maximum RPC buffer size configurable. This would prevent a rogue client from bringing down the NameNode (or other Hadoop daemon) with a few requests for 2 GB buffers. It would also make it easier to debug issues with super-large RPCs or malformed headers, since OOMs can be difficult for developers to reproduce. -- This message is automatically generated by JIRA.
