>             Project: Hive
>          Issue Type: Bug
>          Components: Clients, Server Infrastructure
>    Affects Versions: 3.1.1
>         Environment: CentOS 7.8 
> Hadoop 3.1.1
> Impala 3.4.0
>            Reporter: JungHyun An
>            Priority: Minor
>
> Now we using hive 3.1.1
>  
> Currently in our hive we have tables with hundreds of partitions and hundreds of gigabytes of data.
>  
> When updating the column information of the corresponding table, it was confirmed that the performance was several tens of times slower than the Hive 1.1 version of the existing CDH.
>  
> I would like to ask if there is any architectural change that makes column updates slower than Hive 1 in Hive 3 and later versions.
>  
> Thank you.
