I agree to your suggestion. There is no DDL to change both of them at the same time but this can be done in single Alter_table() API in HMS . Spark is changing SD and table properties at the same time through HMS API. http://gerrit.cloudera.org:8080/#/c/21971/1/fe/src/main/java/org/apache/impala/catalog/events/MetastoreEvents.java@1948 PS1, Line 1948: if (isTrivialSdPropsChanged(beforeTable.getSd(), afterTable.getSd())) { : skipFileMetadata = true; : } else { > The logic could be a bit simpler if isCustomTblPropsChanged() would return Ack -- To view, visit http://gerrit.cloudera.org:8080/21971 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ia969dd32385ac5a1a9a65890a5ccc8cd257f4b97 Gerrit-Change-Number: 21971 Gerrit-PatchSet: 2 Gerrit-Owner: Sai Hemanth Gantasala <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Reviewer: Sai Hemanth Gantasala <[email protected]> Gerrit-Comment-Date: Wed, 30 Oct 2024 21:01:35 +0000 Gerrit-HasComments: Yes
