Haibo Chen commented on HADOOP-13866:
-------------------------------------
I suspect it is this code in DtpHttp2FrameListener
{code:java}
encoder.writeHeaders(ctx, streamId,
new DefaultHttp2Headers().status(HttpResponseStatus.OK.codeAsText()), 0,
false, ctx.newPromise());
{code}
Inspecting the source code in 4.1.0.Beta5, the Http2ConnectionHandler
constructor that is called in hadoop instantiates some default implementations.
However, the constructor is removed from 4.1.1.Final. We can add code in hadoop
to instantiate default implementations and pass them to new
Http2ConnectionHandler constructor.
> Upgrade netty-all to 4.1.1.Final
