tables
Key: IMPALA-12672
URL: https://issues.apache.org/jira/browse/IMPALA-12672
Project: IMPALA
Issue Type: Bug
Components: Catalog
Affects Versions: Impala 4.1.0

If HMS integration is not enabled in Kudu, Impala catalogd loads a kudu table
will change column comments in HMS to 'NULL'.
How to reproduce:
# create a kudu table with some column comments;
# check out comments in database of Hive Metastore;
# executing 'show create table xxx' or some other ddls;
# check out comments again, and it will be replaced with 'NULL';
Newly created kudu table:

After 'show create table kudu_test3' executed:
