> Statistics: NPE when getting Date column partition statistics
> -------------------------------------------------------------
>
> Key: HIVE-20098
> URL: https://issues.apache.org/jira/browse/HIVE-20098
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Standalone Metastore
> Affects Versions: 1.2.1, 4.0.0
> Environment: Tested on versions `1.2.1` and the latest 4.0.0-SNAPSHOT
> Reporter: Andy Rosa
> Assignee: Andy Rosa
> Priority: Major
> Attachments:
> 0001-Fix-NPE-when-getting-statistics-for-date-column.patch, HIVE-20098.1.patch
>
>
> The issue reproduces only for a date column for a partitioned table. It
> reproduces only if the date column has all the values set to null, and if the
> partition is not empty.
> Here is a quick reproducer:
>
>
> {code:java}
> CREATE TABLE dummy_table (
> c_date DATE,
> c_bigint BIGINT
> )
> PARTITIONED BY (ds STRING);
> INSERT OVERWRITE TABLE dummy_table PARTITION (ds='2018-01-01') SELECT
> CAST(null AS DATE), CAST(null AS BIGINT) FROM <any non empty table>;
> ANALYZE TABLE dummy_table COMPUTE STATISTICS FOR COLUMNS;
> DESCRIBE FORMATTED dummy_table.c_bigint PARTITION (ds='2018-01-01');
> DESCRIBE FORMATTED dummy_table.c_date PARTITION (ds='2018-01-01');
> {code}
>
>
> The first `DESCRIBE FORMATTED` statement succeeds, when the second fails with
> an `NPE`
>
> It happens because the null check is missing when converting Object from the
> ObjectStore to the Thrift object. The null check is missing only in the date
> statistics conversion for the partitioned table.
> Missing:
