Subject [jira] [Created] (IMPALA-5351) Handle column comments for Kudu tables
Date Mon, 22 May 2017 17:46:04 GMT
Thomas Tauber-Marshall created IMPALA-5351:

             Summary: Handle column comments for Kudu tables
                 Key: IMPALA-5351
             Project: IMPALA
          Issue Type: Improvement
          Components: Catalog
    Affects Versions: Impala 2.9.0
            Reporter: Thomas Tauber-Marshall

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.
