In my NiFi cluster environment, for a given flow, each node in the cluster is producing afinal FlowFile that is written to HDFS. I needed to append NodeID to filename attribute (e.g., node1_filename1.tar) so that files written to HDFS has unique name and I can easily identify which node produced those files. it would be if NiFi has build in support to add NodeID as common attribute for each FlowFile that can be used by any processors. Thanks Sumanth
