------------------------------------
Summary: RPG can become hung when input port on target NiFi does
not accept files because of backpressure
Key: NIFI-1301
URL: https://issues.apache.org/jira/browse/NIFI-1301
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.4.0
Reporter: Matthew Clarke
If i have an RPG sending to a input port on another NiFi and that input port is
no longer accepting files because of backpressure on the input port connection,
the sending NiFi starts logging that the destination port is full.
The potential problem is that it create a log message for every file that is
queueing up on the connection(s) feeding that RPG destination input port. This
logging seems excess.
The critical issue:
Also when i select "disable transmission" I get the spinning wheel but thread
does not complete. Entire instance is now unresponsive.
Even though it became hung on request to disable transmission, on restart it
started running again. Hung again.
The only options for regaining control is to either restart with auto resume
state set to false or take back pressure off destination input port so thread
can complete.
