Shohei Okumiya commented on HIVE-23390:
---------------------------------------
I can reproduce the issue with Hive 3.1.3 for both table and partition column
statistics.
[https://github.com/okumin/hive/commit/7fe03ca2aa6925349e046d582969aabf83b5b282]
On the master branch, the test for table column statistics passes, where all
`HiveMetaStoreClient#updateTableColumnStatistics` succeeds. The test for
partition column statistics still fails.

> Duplicate entry for a table in TAB_COL_STATS

> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 2.3.4
> Reporter: Mithun Antony
> Priority: Major
>
> When *_analyze <table>_* command was executed from presto to update the stats
> of a table for the first time from multiple cluster sharing the same Hive
> metastore. Duplicate entry for the same table is inserted to the
> *_TAB_COL_STATS_* table.
> This lead to failure executing further *_analyze <table>_* commands.
> {code:java}
> Query failed: Multiple entries with same key:
> dummy=HiveColumnStatistics{integerStatistics=Optional[IntegerStatistics{min=OptionalLong[1],
> max=OptionalLong[1]}], doubleStatistics=Optional.empty,
> decimalStatistics=Optional.empty, dateStatistics=Optional.empty,
