https://community.cloudera.com/t5/Support-Questions/Convert-Hive-Column-type-String-to-Hive-Column-type-struct/m-p/242788#M204587 <P>The hard part here is that Hive returns STRUCT columns as JSON strings, so even if we can parse the JSON, we've lost the type information. It's possible we can retrieve it from the metadata and (if so) create a nested record from the results. Please feel free to file a <A rel="noopener noreferrer noopener noreferrer" href="https://issues.apache.org/jira/projects/NIFI/" target="_blank">Jira</A> for this enhancement.</P> Fri, 19 Apr 2019 09:27:33 GMT mburgess 2019-04-19T09:27:33Z
