----------------------------------
Resolution: Fixed
Fix Version/s: Impala 3.3.0
> 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
> Assignee: HeLifu
> Priority: Major
> Labels: kudu
> Fix For: Impala 3.3.0
>
>
> 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.
