-----------------------------------------
Summary: 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
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.
