Currently {{hive.split.update}} has to be set to {{false}} if a copy-on-write update should be executed when updating an Iceberg table. [https://github.com/apache/hive/blob/0233dcc7f1f09198c093cb4b69bd2b2598c97303/iceberg/iceberg-handler/src/test/queries/positive/update_iceberg_copy_on_write_unpartitioned.q#L1] [https://github.com/apache/hive/blob/0233dcc7f1f09198c093cb4b69bd2b2598c97303/ql/src/java/org/apache/hadoop/hive/ql/parse/UpdateDeleteSemanticAnalyzer.java#L78-L81] Copy-on-write mode should be independent from split update because split update uses positional delete. -- This message was sent by Atlassian Jira (v8.20.10#820010)
