> 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.
