> The logic in 
> org.apache.hudi.table.action.commit.FlinkDeleteHelper#deduplicateKeys does 
> not dedup correctly. 
>  
> Flink/JavaDeleteHelper should merge with HoodieDeleteHelper and change API to 
> use HoodieData. The dedup logic will be fixed along the way. 
> Have dedicated test class for HoodieDeleteHelper will be great.
