Change subject: IMPALA-12156: Support High Availability for Statestore ...................................................................... Patch Set 19: (1 comment) http://gerrit.cloudera.org:8080/#/c/20372/17/bin/start-impala-cluster.py File bin/start-impala-cluster.py: http://gerrit.cloudera.org:8080/#/c/20372/17/bin/start-impala-cluster.py@786 PS17, Line 786: def start_statestore(self): > I'm curious why this implementation looks so different from start_catalogd. For catalogd HA, the two catalog instances don't communicate each other. The active statestored decide which catalogd instance is active. For statestored HA, two statestore instance communicate to negotiate the active role, the active statestored send heartbeat to standby statestored. There are additional port settings for statestore HA. -- To view, visit http://gerrit.cloudera.org:8080/20372 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ibd2c814bbad5c04c1d50c2edaa5b910c82a6fd87 Gerrit-Change-Number: 20372 Gerrit-PatchSet: 19 Gerrit-Owner: Wenzhe Zhou <wz...@cloudera.com> Gerrit-Reviewer: Abhishek Rawat <ara...@cloudera.com> Gerrit-Reviewer: Andrew Sherman <asher...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Jason Fehr <jf...@cloudera.com> Gerrit-Reviewer: Michael Smith <michael.sm...@cloudera.com> Gerrit-Reviewer: Wenzhe Zhou <wz...@cloudera.com> Gerrit-Reviewer: Yida Wu <wydbaggio...@gmail.com> Gerrit-Comment-Date: Tue, 24 Oct 2023 17:56:42 +0000 Gerrit-HasComments: Yes
