> 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.
