Subject [jira] [Created] (HIVE-15374) Hive column comments disappearing/being replaced by "from deserializer"

------------------------------------

             Summary: Hive column comments disappearing/being replaced by "from deserializer"
                 Key: HIVE-15374
                 URL: https://issues.apache.org/jira/browse/HIVE-15374
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: Naveen Gangam
            Assignee: Naveen Gangam


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.
