Sprint: 2022/09/05 (was: 2022/09/05, 2022/09/19)
> Add a boolean parameter to decide whether the partition is cascade or not
> when hive table columns changes
> ---------------------------------------------------------------------------------------------------------

> Key: HUDI-4396
> URL: https://issues.apache.org/jira/browse/HUDI-4396
> Project: Apache Hudi
> Issue Type: Improvement
> Components: hive, meta-sync
> Reporter: XixiHua
> Assignee: XixiHua
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.12.1
>
>
> Currently, when using the HudiHiveSync tool to do hive table columns changes,
> this happens at HMSDDLExecutor.updateTableDefinition(), this cascade is only
> decided by META_SYNC_PARTITION_FIELDS:
> {code:java}
> boolean cascade =
> syncConfig.getSplitStrings(META_SYNC_PARTITION_FIELDS).size() > 0;{code}
> but some scenarios do not need to update partition columns and this will cost
> a lot of time even the hive might hang when the partition number is large.
> Therefore, I want to add a supplement boolean config parameter:
> *HIVE_SYNC_PARTITION_CASCADE_WITH_COLUMN_CHANGE*
> the default is true, if the users don't want to update the partition then set
> it to false
