> I use the following script to test orc column type change with partitioned table on branch-0.13:
> {code}
> use test;
> DROP TABLE if exists orc_change_type_staging;
> DROP TABLE if exists orc_change_type;
> CREATE TABLE orc_change_type_staging (
> id int
> );
> CREATE TABLE orc_change_type (
> id int
> ) PARTITIONED BY (`dt` string)
> stored as orc;
> --- load staging table
> LOAD DATA LOCAL INPATH '../hive/examples/files/int.txt' OVERWRITE INTO TABLE orc_change_type_staging;
> --- populate orc hive table
> INSERT OVERWRITE TABLE orc_change_type partition(dt='20140718') select * FROM orc_change_type_staging limit 1;
> --- change column id from int to bigint
> ALTER TABLE orc_change_type CHANGE id id bigint;
> INSERT OVERWRITE TABLE orc_change_type partition(dt='20140719') select * FROM orc_change_type_staging limit 1;
> SELECT id FROM orc_change_type where dt between '20140718' and '20140719';
> {code}
> if fails in the last query "SELECT id FROM orc_change_type where dt between '20140718' and '20140719';" with exception:

> The value object would be reused each time we deserialize the row, it will fail when we start to process the next path with different schema. Resetting value each time we finish reading one path would solve this problem.
