https://community.cloudera.com/t5/Support-Questions/Apache-nifi-merge-two-different-csv-file-and-create-combine/m-p/235239#M197059 <P>NiFi doesn't do joins in-stream. To accomplish this, I'd recommend processing the first CSV file and storing it in HBase with key=id. You can then process the second csv file, creating a flow to use the id as a query to HBase and get back the reference data from the first CSV.</P><P>If you'd like to do windowed joins, take a look at Streaming Analytics Manager inside of the HDF platform.</P> Sat, 03 Nov 2018 03:36:19 GMT anarasimham 2018-11-03T03:36:19Z
