JungHyun An created HIVE-25698:
----------------------------------
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.
