Background: I'm a new admin to our existing CDP environment. Current prod set up uses Nifi, Ranger, Impala, HMS, Hive on Tez, Isilon/HDFS on Dell Powerscale.  New directive is to create databases and Iceberg tables via S3 using buckets on the same Powerscale in a different access zone and redirect Nifi processes writing to hdfs to write to S3 buckets. Steps: I update the core-site.xml and hive-site.xml files with the following properties - "fs.s3a.secret.key", "fs.s3a.access.key" and "fs.s3a.endpoint". Success: I validated connection to the S3 bucket with aws cli and can run Nifi PutS3Object and the file is in the expected S3 bucket directory. Challenge: I'm getting a error in Impala when I attempt to create an Iceberg table in the same bucket to use with the Nifi PutIceberg processor.
