> I am trying to integrate Apache NiFi with Apache Atlas (ReportLineageToAtlas
> controller service) so that all my datasets and lineages are visible in
> Atlas. I am using NiFi (1.9) and my Lineage strategy is 'Complete Path'. My
> flow is a small test flow which reads a text file from HDFS and pushes
> records to Kafka as well as HDFS. I am seeing following exception:
