             Summary: Query Cache Contains Incorrect Result For Virtual Columns
                 Key: HIVE-21461
                 URL: https://issues.apache.org/jira/browse/HIVE-21461
             Project: Hive
          Issue Type: Bug
    Affects Versions: 3.1.0
            Reporter: Shawn Weeks


Hive query cache will contain incorrect results if query containing virtual columns input__file__name or block__offset__inside__file are run prior to compactions and then run immediately after. Not sure if these should be treated like non-deterministic functions or if it's possible for Hive to know that the underlying data has been rearranged due to compaction.
{code:java}
select count(*), input__file__name
from test_hive_streaming
group by input__file__name;
{code}
