> Key: HIVE-2322
> URL: https://issues.apache.org/jira/browse/HIVE-2322
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Serializers/Deserializers
> Reporter: Sohan Jain

> Attachments: HIVE-2322.1.patch, HIVE-2322.2.patch, HIVE-2322.3.patch,

>
> We store metadata about ColumnarSerDes in the metastore, so it should be
> considered a native SerDe. Then, column information can be retrieved from
> the metastore instead of from deserialization.
> Currently, for non-native SerDes, column comments are only shown as "from
> deserializer". Adding ColumnarSerDe to the list of native SerDes will
> persist column comments. See HIVE-2171 for persisting the column comments of
> custom SerDes.
