---------------------------------------
Resolution: Duplicate
> Dropping database via HiveMetastoreClient involves useless work
> ---------------------------------------------------------------
>
> Key: HIVE-18707
> URL: https://issues.apache.org/jira/browse/HIVE-18707
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 3.0.0, 2.3.3
> Reporter: Alexander Kolbasov
> Assignee: Alexander Kolbasov
> Priority: Major
>
> HiveMetastoreClient has dropDatabase() method which does this:
>
> {code:java}
> if (cascade) {
> List<String> tableList = getAllTables(name);
> for (String table : tableList) {
> try {
> // Subclasses can override this step (for example, for temporary
> tables)
> dropTable(name, table, deleteData, true);
> } catch (UnsupportedOperationException e) {
> // Ignore Index tables, those will be dropped with parent tables
> }
> }
> }{code}
> This isn't needed since the similar thing is done on the server side and just
> wastes time in sending multiple server calls.
>
> [~pvary] [~alangates] FYI.
