Hi @Frank Maritato I am working on a similar use case. Trying to write content of Flowfiles coming in PutParquet directly on S3 bucket. I have mentioned the directory as bucket's path(including folder subdirectory) and have core-site.xml similar to yours(fs.defaultFS has only bucket name). Also, I am using s3a URI scheme instead of s3 (all paths have appropriate URI). Also, I have added jars in 'Additional Resources ' attribute according to this link http://apache-nifi-users-list.2361937.n4.nabble.com/PutParquet-with-S3-td3632.html But on execution I am facing error: 'ERROR PutParquet[Id=...] failed to invoke @OnScheduled method due to java.lang.RunTimeException: Failed while executing one of processor's onScheduled task.; processor will not be scheduled to run for 30 seconds: java.lang.RunTimeException: Failed while executing one of processor's OnScheduled task' On inspection of logs i can see the Error as : 'AmazonS3Exception: Status Code: 400, AWS Service: Amazon S3, AWS Request ID: , AWS Error Code: null, AWS Error Message: Bad Request' I have also mentioned s3a endpoint as s3.ap-south-1.amazonaws.com because I have Nifi server and bucket in the same region, Mumbai Can you help me out with your configuration's or any additional jars?
