------------------------------------
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).
