However FetchParquet will get the .parquet file and put its content in a single flowFile, but it doesn't read each record invidually from the parquet file into a flow files record by record.

@Bryan Bende Do I have to use StandardSSLContextService to connect to IBM mq if my nifi.properties is configured with SSL Authentication for web browser? If I have to, could I use the same certificate that I created for web browser for IBM MQ (I use nifi.pfx for the web browser)? ... View more

1) I had Configured Apache NiFi SSL Authentication using the following instruction https://www.batchiq.com/nifi-configuring-ssl-auth.html I attached the Certificate to a web Browser and the browser is able to connect to Nifi. 2) I have Nifi connected to IBM MQ, and I know I need to configured StandardSSLContextService of JMSConnectionFactoryProvider. 3) My question is that do I need to attach the certificate to MQ? Any suggestion on how to do it? Thanks a lot Andy ... View more
