[jira] [Commented] (HIVE-19016) Vectorization and Parquet: When vectorized, parquet_nested_complex.q produces RuntimeException: Unsupported type used

    [ https://issues.apache.org/jira/browse/HIVE-19016?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16469808#comment-16469808 ] 

Haifeng Chen commented on HIVE-19016:
-------------------------------------

[~vihangk1] I have some research on this. And the nested complex type (nested struct, map and list) is not yet implement in Parquet vectorized reader. I got a study on the details and trying figure out a implementation. I will try to work out a patch.
