-------------------------
Resolution: Duplicate
> Disallow overwriting merge properties during writes
> ---------------------------------------------------
>
> Key: HUDI-9717
> URL: https://issues.apache.org/jira/browse/HUDI-9717
> Project: Apache Hudi
> Issue Type: Sub-task
> Reporter: Lin Liu
> Priority: Critical
> Fix For: 1.1.0
>
>
> Currently Hudi allows users to change merging behavior defined by the table
> config during writes by using write merging configs, including
> 1. hoodie.datasource.write.payload.class
> 2. hoodie.write.record.merge.strategy.id
> 3. hoodie.write.record.merge.mode.
> (Note: Partial_Update_Mode is introduced in 1.1, which does not have
> corresponding write config.)
> Such behavior is risky because
> 1. the merge behavior is non-trackable, and
> 2. it could produce inconsistent data for the table when the overwrite config
> is not compatible with the table configs.
> Hudi should disable such behavior.
