   @adamjoneill I found some related issues to querying nested parquet fields 
in Presto - https://github.com/prestodb/presto/pull/10852, 
https://github.com/prestodb/presto/pull/9156, 
https://github.com/prestodb/presto/pull/10849 . I am wondering if your use case 
might be one of those backward compatibility cases. I am yet to reproduce this. 
Have you already looked into these threads to see if there are any leads ? 
   
   My guess at the moment - there is some expectation with complex nested type 
schema that Presto parquet reader expects that mismatches with the actual data. 
Need to dig this further to check if its a bug or a schema issue.
