---------------------------------
Priority: Blocker (was: Critical)
> Need a way to configure TNonblockingServer.maxReadBufferBytes to prevent OOMs
> from network misbehavour
> ------------------------------------------------------------------------------------------------------

> Key: ACCUMULO-2360
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2360
> Project: Accumulo
> Issue Type: Bug
> Components: master, tserver
> Affects Versions: 1.5.0
> Reporter: John Vines
> Assignee: John Vines
> Priority: Blocker
> Fix For: 1.5.1, 1.6.0
>
>
> 1.5.0 introduced GENERAL_MAX_MESSAGE_SIZE (ACCUMULO-1141), a parameter to set
> the maximum frame size for the TFramedTransport. However, there is an
> underlying frame (I think this is a glossary conflict) read in
> TNonblockingServer that can still cause OOM errors if erroneously connected
> to (telnet, netcat, etc.), creating a stack trace as such
> {code}2014-02-12 10:26:40,439 [util.TServerUtils$THsHaServer] ERROR: run()
> exiting due to uncaught error
> java.lang.OutOfMemoryError: Java heap space
> at java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:57)
> at java.nio.ByteBuffer.allocate(ByteBuffer.java:329)

> at
> org.apache.thrift.server.TNonblockingServer$SelectAcceptThread.run(TNonblockingServer.java:154){code}
> I believe if we set maxReadBufferBytes to the server arguments, it will
> filter appropriately. The only decision I'm not sure about is if we should
> recycle the max message property or have a separate one.
