----------------------------------
Summary: Compute partition column stats fails if partition col
type is date
Key: HIVE-10231
URL: https://issues.apache.org/jira/browse/HIVE-10231
Project: Hive
Issue Type: Bug
Components: Statistics
Affects Versions: 1.0.0
Reporter: Chaoyu Tang
Assignee: Chaoyu Tang
Fix For: 1.2.0
Currently the command "analyze table .. partition .. compute statistics for
columns" may only work for partition column type of string, numeric types, but
not others like date. See following case using date as partition coltype:
{code}
create table colstatspartdate (key int, value string) partitioned by (ds date,
hr int);
insert into colstatspartdate partition (ds=date '2015-04-02', hr=2) select key,
value from src limit 20;
analyze table colstatspartdate partition (ds=date '2015-04-02', hr=2) compute
statistics for columns;
{code}
you will get RuntimeException:
{code}
FAILED: RuntimeException Cannot convert to Date from: int
15/04/06 17:30:01 ERROR ql.Driver: FAILED: RuntimeException Cannot convert to
Date from: int
