-------------------------------------------
Summary: Handle translated external Kudu tables
Key: IMPALA-9030
URL: https://issues.apache.org/jira/browse/IMPALA-9030
Project: IMPALA
Issue Type: Bug
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
In HIVE-22158 HMS disallows creating of any managed table which is not
transactional. This breaks the behavior for managed Kudu tables created from
Impala. When user creates a managed Kudu table, HMS internally translates such
table into a external table with an additional property
"TRANSLATED_TO_EXTERNAL" set to true. The table type is changed to EXTERNAL.
Subsequently, when such a table is dropped or renamed, Catalog thinks such
tables as external and does update Kudu (dropping the table in Kudu or renaming
the table in Kudu). This is unexpected from the point of view of user since
user may think that they created a managed table and Impala should handle the
drop and rename accordingly. The same applies to certain other alter operations
like alter table set properties on a managed Kudu table which previously was
disallowed now goes through after HIVE-22158
