Patch Set 2: (3 comments) http://gerrit.cloudera.org:8080/#/c/21520/2/be/src/statestore/statestore-subscriber.h File be/src/statestore/statestore-subscriber.h: http://gerrit.cloudera.org:8080/#/c/21520/2/be/src/statestore/statestore-subscriber.h@345 PS2, Line 345: return MonotonicMillis() - last_failover_time_.Load(); nit: Might be nice to DCHECK that the result is not negative. http://gerrit.cloudera.org:8080/#/c/21520/2/be/src/statestore/statestore-subscriber.cc File be/src/statestore/statestore-subscriber.cc: http://gerrit.cloudera.org:8080/#/c/21520/2/be/src/statestore/statestore-subscriber.cc@1098 PS2, Line 1098: bool has_failover_before = last_failover_time_.Load() > 0; Do we really need to check this? If it's 0, then MilliSecondsSinceLastFailover will be a very large number and not less than statestore_subscriber_recovery_grace_period_ms. Right now it means we read from an atomic twice in a row. http://gerrit.cloudera.org:8080/#/c/21520/2/tests/custom_cluster/test_statestored_ha.py File tests/custom_cluster/test_statestored_ha.py: http://gerrit.cloudera.org:8080/#/c/21520/2/tests/custom_cluster/test_statestored_ha.py@692 PS2, Line 692: assert False, "Query expected to fail" Can we verify that it had to wait longer than the CANCELLATION_GRACE_PERIOD_S for the query to fail? -- To view, visit http://gerrit.cloudera.org:8080/21520 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I720bec5199df46475b954558abb0637ca7e6298b Gerrit-Change-Number: 21520 Gerrit-PatchSet: 2 Gerrit-Owner: Wenzhe Zhou <[email protected]> Gerrit-Reviewer: Abhishek Rawat <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Michael Smith <[email protected]> Gerrit-Reviewer: Riza Suminto <[email protected]> Gerrit-Reviewer: Wenzhe Zhou <[email protected]> Gerrit-Comment-Date: Fri, 14 Jun 2024 21:25:21 +0000 Gerrit-HasComments: Yes
