-----------------------------
Summary: Allow control over unexpected failure behavior in
processors
Key: NIFI-12882
URL: https://issues.apache.org/jira/browse/NIFI-12882
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: saarbs
Recently we had a problem with a flow using UpdateAttribute that does
base64decode, and one of our flow sources began sending invalid base64. This
resulted in exceptions in the processor causing rollbacks to the flowfiles and
backpressure in the flow.
Since there is no failure relationship to the processor there was no way to
resolve this issue, And we realized there are a lot of processors facing this
issue where an unexpected failure could cause an infinite loop where some flows
may desire to send them to a failure relationship.
I suggest a setting or an unexpected failure relationship, which would allow
keeping the existing behavior of a rollback but would also allow terminating or
processing the failure in different ways.
