Patch Set 3: (2 comments) http://gerrit.cloudera.org:8080/#/c/23592/2/docs/topics/impala_sync_hms_events_strict_mode.xml File docs/topics/impala_sync_hms_events_strict_mode.xml: http://gerrit.cloudera.org:8080/#/c/23592/2/docs/topics/impala_sync_hms_events_strict_mode.xml@36 PS2, Line 36: of the query coordinator > Does failing the query produce error? Might be good to show an example outp There are some examples in the tests, e.g. https://github.com/apache/impala/blob/2688e30ae51d90de6d9e061b75a2f7bc4af24892/tests/custom_cluster/test_events_custom_configs.py#L1902 The error message is "Failed to sync events from Metastore:" + the reason, e.g. "Failed to sync events from Metastore: HMS event processing is disabled". http://gerrit.cloudera.org:8080/#/c/23592/3/docs/topics/impala_sync_hms_events_wait_time_s.xml File docs/topics/impala_sync_hms_events_wait_time_s.xml: http://gerrit.cloudera.org:8080/#/c/23592/3/docs/topics/impala_sync_hms_events_wait_time_s.xml@58 PS3, Line 58: SELECT * FROM my_updated_table; We can use a better example that shows the relative operation in Hive. E.g. the table is updated by an INSERT on dynamic partitions in Hive. To safely query the table immediately in Impala after the Hive statement finishes, add this query option: hive> insert into tbl partition(p) select * from tbl2; impala> set sync_hms_events_wait_time_s=300; impala> select * from tbl; In this example, client side don't need REFRESH or explicit wait. -- To view, visit http://gerrit.cloudera.org:8080/23592 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ia11663c5e84794d4bca658124cde59bf97aa7158 Gerrit-Change-Number: 23592 Gerrit-PatchSet: 3 Gerrit-Owner: Sanjana Malhotra <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Pranav Lodha <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Comment-Date: Thu, 06 Nov 2025 02:35:26 +0000 Gerrit-HasComments: Yes
