> After creating a table in hive with column comments, running show create table or describe
[formatted], on the same table gives "from deserializer" instead of the original comments.

> CREATE TABLE `test`(
>   `stringid` string COMMENT 'string id', 
>   `value` string COMMENT 'description')
> ROW FORMAT SERDE 
>   'org.apache.hadoop.hive.contrib.serde2.RegexSerDe' 
> WITH SERDEPROPERTIES ( 
>   'input.regex'='(.{1})');
> The comments appear to be stored correctly in the HMS backend DB. Just the fetching of
this metadata seems to be incorrect.
