> NPE aggregating column statistics for date column in partitioned table
> ----------------------------------------------------------------------
>
> Key: HIVE-14773
> URL: https://issues.apache.org/jira/browse/HIVE-14773
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 2.2.0
> Reporter: Nita Dembla
> Assignee: Pengcheng Xiong
> Attachments: HIVE-14773.01.patch
>
>
> Hive runs into a NPE when the query has a filter on a date column and the
> partitioned column
> eg:
> {code}
> create table date_dim (d_date date) partitioned by (d_date_sk bigint) stored
> as orc;
> set hive.exec.dynamic.partition.mode=nonstrict;
> insert into date_dim partition(d_date_sk=2416945) values('1905-04-09');
> insert into date_dim partition(d_date_sk=2416946) values('1905-04-10');
> insert into date_dim partition(d_date_sk=2416947) values('1905-04-11');
> analyze table date_dim partition(d_date_sk) compute statistics for columns;
> explain select count(*) from date_dim where d_date > date "1900-01-02" and
> d_date_sk= 2416945;
> {code}
> Here d_date_sk is a partition column and d_date is of type date.
