Mithun Radhakrishnan commented on HIVE-10598:
---------------------------------------------
Hey, Gopal. Thanks for looking at this. I'm afraid I'm seeing this on trunk and
on YHive 0.13 (which is very close to 0.14). The stack trace is for trunk.
> Vectorization borks when column is added to table.

> Key: HIVE-10598
> URL: https://issues.apache.org/jira/browse/HIVE-10598
> Project: Hive
> Issue Type: Bug
> Components: Vectorization
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan

> Consider the following table definition:
> {code:sql}
> create table foobar ( foo string, bar string ) partitioned by (dt string)
> stored as orc;
> alter table foobar add partition( dt='20150101' ) ;
> {code}
> Say the partition has the following data:
> {noformat}
> 1 one 20150101
> 2 two 20150101
> 3 three 20150101
> {noformat}
> If a new column is added to the table-schema (and the partition continues to
> have the old schema), vectorized read from the old partitions fail thus:
> {code:sql}
> alter table foobar add columns( goo string );
> select count(1) from foobar;
> {code}
