> With https://issues.apache.org/jira/browse/HIVE-7554 a unfortunate else branch was introduced to org.apache.hadoop.hive.ql.io.parquet.read.DataWritableReadSupport . That else branch fired an exception in case the parquet file schema had less fields than the table schema. So adding columns to a parquet backed table and query the added columns on old partitions wasn't possible anymore. Which was very unfortunate for my team. https://issues.apache.org/jira/browse/HIVE-7800 fixed that, see point 3 in Daniel Weeks' comment https://issues.apache.org/jira/browse/HIVE-7800?focusedCommentId=14158594&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14158594 .
> However Hive-7800 did not introduce a test case for that. I'd love to see one.
> Best,
> Manuel
