Subject [jira] [Commented] (HIVE-20721) Describe table sometimes shows "from deserializer" for column comments
Date Thu, 11 Oct 2018 03:17:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-20721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16645899#comment-16645899

Xuefu Zhang commented on HIVE-20721:
------------------------------------

Hi [~Ballesteros], have you tried "desc table" for your table as that's what HIVE-6681 was
about?

>             Project: Hive
>          Issue Type: Bug
>          Components: Serializers/Deserializers
>    Affects Versions: 1.1.0
>            Reporter: Pedro
>            Priority: Major

> When we want to see the comments made in the hive tables, it only shows "from deserializer"
>  
> For example
> > show create table table_name
> CREATE EXTERNAL TABLE `table_name`(
>  `some_column1` bigint COMMENT 'from deserializer', 
>  `some_column2` string COMMENT 'from deserializer', 
>  `some_column3` string COMMENT 'from deserializer',
> [...]
> PARTITIONED BY ( 
>  `dt` string)
> ROW FORMAT SERDE 
>  'org.apache.hive.hcatalog.data.JsonSerDe' 
> STORED AS INPUTFORMAT 
>  'org.apache.hadoop.mapred.TextInputFormat' 
> OUTPUTFORMAT 
>  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
> LOCATION
>  'hdfs://location/table_name'
> TBLPROPERTIES (
>  'json.schema.url'='/location/json/table_name.json', 
>  'transient_lastDdlTime'='1525858710')
>  
> I saw it was resolved in HIVE-6681 but the fixed version was 0.13.0. I'm on 1.1.0 and
apparently I have the same issue.
