---------------------------------
Summary: ExecuteStreamCommand should have a failure relationship
Key: NIFI-4559
URL: https://issues.apache.org/jira/browse/NIFI-4559
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Affects Versions: 1.4.0
Reporter: Joseph Witt
ExecuteStreamCommand only has a success relationship. The gist is it executes
the command, captures the output stream, code, etc.. and stores the necessary
content and attributes.
However, for those wanting to see the status code as an indicator of failure
they have to create a flow which checks, loops, etc.. This is more work than
necessary since the processor can provide a better indicator. By adding a
failure relationship we can route results and status codes for non-zero to this
relationship. We'll have to consider backward compatibility friendly ideas but
the gist is to make this common failure/retry pattern easier to configure and
track.
