Prasanth Jayachandran updated HIVE-14355:
-----------------------------------------
Status: Patch Available (was: Open)
> Schema evolution for ORC in llap is broken for int to string conversion
> -----------------------------------------------------------------------
>
> Key: HIVE-14355
> URL: https://issues.apache.org/jira/browse/HIVE-14355
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.1.0, 2.2.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Critical
> Attachments: HIVE-14355-java-only.patch, HIVE-14355.1.patch
>
>
> When schema is evolved from any integer type to string then following
> exceptions are thrown in LLAP (Works fine in Tez). I guess this should happen
> even for other conversions.
> {code}
> hive> create table orc_integer(b bigint) stored as orc;
> hive> insert into orc_integer values(100);
> hive> select count(*) from orc_integer where b=100;
> OK
> 1
> hive> alter table orc_integer change column b b string;
> hive> select count(*) from orc_integer where b=100;
> // FAIL with following exception
> {code}
