tables
[ https://issues.apache.org/jira/browse/IMPALA-5351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16810853#comment-16810853 ]
Grant Henke commented on IMPALA-5351:
-------------------------------------
Kudu now supports column comments (see KUDU-1711).
> Handle column comments for Kudu tables
> --------------------------------------
>
> Key: IMPALA-5351
> URL: https://issues.apache.org/jira/browse/IMPALA-5351
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Affects Versions: Impala 2.9.0
> Reporter: Thomas Tauber-Marshall
> Priority: Major
> Labels: kudu
>
> Currently, if a column comment is specified in a CREATE TABLE for a Kudu table, we just silently drop it because Kudu does not currently support column comments (KUDU-1711).
> One option would be to store the comments in HMS, but splitting the metadata between HMS and Kudu is probably more complicated than its worth.
> Most likely, we can just wait for it to be implemented on the Kudu side, but before then we may want to consider issuing a warning when people use column comments on Kudu tables.
