Different level used for log and audit in BaseAtlasModule.processSeparateField(AtlasSession, Mapping, Field, Field)

[apupier]

there is a warn and a log, which one should be used?

            LOG.warn(String.format("Separate requires zero or positive Index value to be set on outputField outputField.path=%s",
                    outputField.getPath()));
            addAudit(session, outputField.getDocId(),
                    String.format("Separate requires zero or positive Index value to be set on outputField outputField.path=%s",
                            outputField.getPath()),
 outputField.getPath(), AuditStatus.ERROR, null);

Logging, Audits and Validations weren't meant to be the same thing, so variance in 'level' betwen them isn't necessarily incorrect. Due to time constraints, the final behaviors were never finalized. See (#7)
