[HBASE-15212] RPCServer should enforce max request size

• Type: Improvement
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 1.3.0, 0.98.19, 2.0.0
• Hadoop Flags: Reviewed

Release Note

Adds a configuration parameter "hbase.ipc.max.request.size" which defaults to 256MB to protect the server against very large incoming RPC requests. All requests larger than this size will be immediately rejected before allocating any resources (memory allocation, etc).

Description

A TODO from HBASE-15177 was that we are not protecting the RPCServer in case an RPC request with a very large size is received. This might cause the server to go OOM because we are allocating the RPC serialization into a BB. Instead we should reject the RPC and close the connection.
