Subject [jira] [Commented] (SPARK-17910) Allow users to update the comment of a column
Date Fri, 21 Oct 2016 09:24:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-17910?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15594610#comment-15594610
] 

Jiang Xingbo commented on SPARK-17910:
--------------------------------------

[~yhuai] Seems we don't support `ALTER TABLE CHANGE COLUMN` statements currently, do we plan
to support that? Are there any discussions I can refer to? Thank you!

> Right now, once a user set the comment of a column with create table command, he/she
cannot update the comment. It will be useful to provide a public interface (e.g. SQL) to do
that.
