Koji Kawamura commented on NIFI-2567:
-------------------------------------
HTTP Site-to-Site POST uses HttpAsyncRequestProducer. Its produceContent method
reads data from dataPacketChannel which Remote Group Port sends data to.
The produceContent method has a loop inside, to read data from the channel, and
write buffer by calling encoder.write. However, in order to use the Async
framework properly, the method should return when encoder.write returns 0, even
if there's remaining buffer.
ContentEncoder.write possibly returns 0, if underlying session is not ready to
send more data. When it's ready, the produceContent method will be called
again. Current implementation doesn't take this into account, so it the loop
runs infinitely.
I fixed the code, confirmed it can send more data. I will send a PR once an
Unit test case is added.
