------------------------------------

             Summary: UINT32 Parquet columns are handled as signed INT32-s, silently reading incorrect data
                 Key: HIVE-17843
                 URL: https://issues.apache.org/jira/browse/HIVE-17843
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltan Ivanfi


An unsigned 32 bit Parquet column, such as

{noformat}
optional int32 uint_32_col (UINT_32)
{noformat}

is read by Hive as if it were signed, leading to incorrect results.
