Patch Set 11: (1 comment) http://gerrit.cloudera.org:8080/#/c/17697/10/fe/src/main/java/org/apache/impala/catalog/CatalogServiceCatalog.java File fe/src/main/java/org/apache/impala/catalog/CatalogServiceCatalog.java: http://gerrit.cloudera.org:8080/#/c/17697/10/fe/src/main/java/org/apache/impala/catalog/CatalogServiceCatalog.java@2131 PS10, Line 2131: partsToBeRefreshed = > @Yu-Wen: If there are multiple getOrLoad requests that end up at line 2131 @Sourabh Thanks for the suggestion. I will try if I can do something like loadAsync. For refreshFileMetadata(), Vihang pointed out a potential race condition that we cannot make sure the whole table reloading was happened after a compaction or not. It is possible we end up still serve stale file metadata. To avoid more issues around race conditions, we'd need to refresh file metadata even there is a concurrent full table reloading. -- To view, visit http://gerrit.cloudera.org:8080/17697 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I86a112a77980fef7f6238978bc9668a65262101e Gerrit-Change-Number: 17697 Gerrit-PatchSet: 11 Gerrit-Owner: Yu-Wen Lai <yu-wen....@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Sourabh Goyal <soura...@cloudera.com> Gerrit-Reviewer: Vihang Karajgaonkar <vih...@cloudera.com> Gerrit-Reviewer: Yu-Wen Lai <yu-wen....@cloudera.com> Gerrit-Comment-Date: Fri, 30 Jul 2021 16:58:57 +0000 Gerrit-HasComments: Yes
