I do not quite follow why do we need to drop the hms table entry? Will the drop table in HMS also trigger drop table in Kudu? If you are testing the corner case when the entry is not present in HMS, maybe add more comment here to be more clear. Can we have a most common rename table test case without any corner cases? http://gerrit.cloudera.org:8080/#/c/8312/6/src/kudu/integration-tests/master_hms-itest.cc@245 PS6, Line 245: ASSERT_OK(table_alterer->RenameTo(renamed_table_name)->Alter()); Assert table id/master addresses/table schema. http://gerrit.cloudera.org:8080/#/c/8312/6/src/kudu/integration-tests/master_hms-itest.cc@285 PS6, Line 285: ASSERT_OK(hms_client_->AlterTable(hms_database_name, hms_table_name, hms_table)); So alter column through HMS would not affect the table schema stored in Kudu? http://gerrit.cloudera.org:8080/#/c/8312/7/src/kudu/master/hms_catalog.cc File src/kudu/master/hms_catalog.cc: http://gerrit.cloudera.org:8080/#/c/8312/7/src/kudu/master/hms_catalog.cc@164 PS7, Line 164: create it in the HMS I am not sure it is good to create a HMS entry if not present.
