Change subject: IMPALA-7665: Fix unwarranted query cancellation on statestore restart ...................................................................... IMPALA-7665: Fix unwarranted query cancellation on statestore restart Currently, if the statestore restarts and disseminates an inconsistent view of cluster membership to the coordinators, then they might believe that the backends no longer in the membership update are down and would start canceling queries that are running or scheduled to run on those allegedly failed backends. This patch adds a grace period after statestore recovery/successful registration that give it enough time to gather a consistent state of the cluster. Testing: Added an e2e test Change-Id: I30b68bd8bde4bf589d58d42d6f683afb166de959 --- M be/src/service/impala-server.cc M be/src/statestore/statestore-subscriber.cc M be/src/statestore/statestore-subscriber.h M tests/custom_cluster/test_restart_services.py 4 files changed, 66 insertions(+), 2 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/61/13061/1 -- To view, visit http://gerrit.cloudera.org:8080/13061 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I30b68bd8bde4bf589d58d42d6f683afb166de959 Gerrit-Change-Number: 13061 Gerrit-PatchSet: 1 Gerrit-Owner: Bikramjeet Vig <[email protected]>
