Change subject: IMPALA-12513: Reset metadata when the CatalogD become active ...................................................................... Patch Set 4: (1 comment) http://gerrit.cloudera.org:8080/#/c/20614/2//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/20614/2//COMMIT_MSG@9 PS2, Line 9: the loaded metadata in the candidate : CatalogD may not be the latest. > There are serveral causes why the metadata loaded in the standby catalogd l For "The catalogd enables load metadata in the background", we can enable "load_catalog_in_background" for standby catalogd, though it increase the network traffic. For "Newly created user-defined functions will not be recognized after failover", this issue is tracked by IMPALA-10273 (Support function event). Since most of the users don't turn on load_catalog_in_background and don't create UDFs in ETL jobs, I prefer to add a flag reset_catalog_when_active. -- To view, visit http://gerrit.cloudera.org:8080/20614 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2b54f36f96e7901499105e51790d8e2300d7fea9 Gerrit-Change-Number: 20614 Gerrit-PatchSet: 4 Gerrit-Owner: ttttttz <2433038...@qq.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Quanlong Huang <huangquanl...@gmail.com> Gerrit-Reviewer: Wenzhe Zhou <wz...@cloudera.com> Gerrit-Reviewer: ttttttz <2433038...@qq.com> Gerrit-Comment-Date: Wed, 01 Nov 2023 03:32:08 +0000 Gerrit-HasComments: Yes
