-----------------------------
Seemed HIVE-2332 and working well in trunk. Could you try?
> Hive cannot support following query, and will throw
> java.lang.IndexOutOfBoundsException in
> org.apache.hadoop.hive.serde2.objectinspector.StandardStructObjectInspector

> Key: HIVE-4237
> URL: https://issues.apache.org/jira/browse/HIVE-4237
> Project: Hive
> Issue Type: Bug
> Components: Query Processor, Serializers/Deserializers
> Affects Versions: 0.9.0
> Environment: Hive 0.9.0 on JDK 1.6.0_35
> Reporter: Yong Zhang
> Priority: Minor
>
> Recently, I was helping one of my colleague to fix one Hive issue. I have to
> admit that the query didn't do what was planned, but I don't think it should
> break the hive.
> For a hive table, the following query will break
> select count(distinct columnA), columnB from table group by columnA, columnB
> I know the correct query should be
> select count(distinct columnA), columnB from table group by columnB
> But even in the incorrect query, hive should return me 1 as the unique count
> of columnA for every columnB, but instead, it breaks with the following stack
> trace:
> Caused by: java.lang.IndexOutOfBoundsException: Index: 2, Size: 2
> at java.util.ArrayList.RangeCheck(ArrayList.java:547)
> at java.util.ArrayList.get(ArrayList.java:322)
