We were looking at utilizing DataProc for a managed Hadoop service. We are currently managing our own managed Hadoop for HDFS while using Nifi to write to and read from HDFS. The HDFS Processors utilize kerberos authentication methods while DataProc uses IAM auth. We were wondering if anyone has run into the same issue and if so how they dealt with it? We are looking at maybe creating a new IAM controller in Nifi and allowing the Processors to use it. Any feedback/ideas would definitely be appreciated.
