[jira] [Commented] (HIVE-4703) WebHcat looses column comments and
returns 'from deserializer'
[ https://issues.apache.org/jira/browse/HIVE-4703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13680088#comment-13680088 ]
Eugene Koifman commented on HIVE-4703:
--------------------------------------
Executing the same create table from Hive CLI shell works fine.
This may be related to HIVE-4449, but repro steps there are not specified.
