----------------------------------

             Summary: Hive column update performance too low when table partition over 700
                 Key: HIVE-25698
                 URL: https://issues.apache.org/jira/browse/HIVE-25698
             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
             Fix For: All Versions


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.
