Branky Shao commented on HIVE-6565:
-----------------------------------
Xuefu Zhang thanks for following up. I got few problems when I work on
Cascading and Hive/HCatalog
integration(https://github.com/branky/cascading.hive). They can be fixed along
with HIVE-6163 (was also reported by me) and HIVE-5728. I did patch on my own
fork of
Hive(https://github.com/branky/hive/commit/20c62b3ec73a55d84eeffca6eab4af066e04e22a)
to make the integration work.
Regarding this issue, I found the fix may not be that simple. OrcSerde is
included in ql module which depend on serde module actually. Then it will cause
cyclic dependency. I would cancel this issue and try to find other workaround.
> OrcSerde should be added as NativeSerDe in SerDeUtils

> Key: HIVE-6565
> URL: https://issues.apache.org/jira/browse/HIVE-6565
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Affects Versions: 0.12.0
> Reporter: Branky Shao
>
> If the table defined as ORC format, the columns info can be fetched from
> StorageDescriptor, no need to get from SerDe.
> And obviously, ORC is a Hive's native file format, therefore, OrcSerde should
> be added as NativeSerDe in SerDeUtils.
> The fix is fairly simple, just add single line in SerDeUtils :
> nativeSerDeNames.add(org.apache.hadoop.hive.ql.io.orc.OrcSerde.class.getName());
