             Summary: Impala writing data to tables should not lead to incorrect results in Hive
                 Key: IMPALA-8839
                 URL: https://issues.apache.org/jira/browse/IMPALA-8839
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 3.3.0
            Reporter: Yongzhi Chen
            Assignee: Yongzhi Chen


This include partitioned/unpartitioned tables:
The proposed solution for this issue is that when Impala writes data to an unpartitioned table, it should update 'COLUMN_STATS_ACCURATE' json structure in table properties by removing its 'COLUMN_STATS' nested field (this will end up in TABLE_PARAMS table in HMS).

The proposed solution for this issue is that when Impala writes data to a partitioned table, it should update 'COLUMN_STATS_ACCURATE' json structure by removing its 'COLUMN_STATS' nested field in the properties of the partitions where data was inserted (PARTITION_PARAMS table in HMS).
