-----------------------------------
Summary: HTTP Site-to-Site fails with
java.nio.channels.AsynchronousCloseException when sending through proxy that
requires authentication
Key: NIFI-2525
URL: https://issues.apache.org/jira/browse/NIFI-2525
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.0.0
Reporter: Koji Kawamura
Pulling data using Remote Process Group from output port works.
However, pushing data using Remote Process Group to input port fails with
AsynchronousCloseException.
A RPG sends data via POST, then a proxy server returns 407: proxy auth
required. After this, the RPG should resend the request with credential, but
the data channel is already closed.
Currently, it uses chunked encoding so that it can stream data to send. Sending
actual data twice won't be efficient. We need to do the authentication before
start reading flow-file stream.
