Vihang Karajgaonkar commented on IMPALA-8751:
---------------------------------------------
The notification log event messages are by default compressed in Hive 3.x. In
order to fix this the event listener will have to uncompress the event message.
Unfortunately, the encoder and decoder libraries provided by HMS are available
out of the box for Java client {{HiveMetastoreClient}}. In this particular
case, it looks like the the c++ event listener will have to decompress the
message on its own.

> Key: IMPALA-8751
> URL: https://issues.apache.org/jira/browse/IMPALA-8751
> Project: IMPALA
> Issue Type: Bug
> Affects Versions: Impala 3.3.0
> Reporter: Yongzhi Chen
> Priority: Major
>
> For example in some kudu integration test as:
> TestKuduHMSIntegration.test_drop_db_cascade in custom_cluster/test_kudu.py
> It failed with:
> custom_cluster/test_kudu.py:239: in test_drop_db_cascade
> assert not kudu_client.table_exists(kudu_table.name)
> /usr/lib/python2.7/contextlib.py:35: in __exit__
> self.gen.throw(type, value, traceback)
> common/kudu_test_suite.py:165: in temp_kudu_table
> kudu.delete_table(name)
> kudu/client.pyx:392: in kudu.client.Client.delete_table (kudu/client.cpp:7106)
> ???
> kudu/errors.pyx:56: in kudu.errors.check_status (kudu/errors.cpp:904)
> ???
> E KuduNotFound: failed to drop Hive Metastore table: TException - service
> has thrown: NoSuchObjectException(message=s7mo1z)
> And when trying to add default capabilities to kudu tables, it is sometime
> effective, sometimes not:
> For example after enable default kudu OBJCAPABILITIES,
> ./run-tests.py metadata/test_ddl.py -k "create_kudu" will succeed while same
> test in
> ./run-tests.py custom_cluster/test_kudu.py :
> {noformat}
