    Description

      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.
