[jira] [Created] (HUDI-4396) Add a boolean parameter to decide whether the partition is cascade or not when hive table columns changes

XixiHua created HUDI-4396:
-----------------------------

             Summary: 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
            Reporter: XixiHua


Currently, when using the HudiHiveSync and DataHubSyncTool tools 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 but 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: 

*PARTITION_CASCADE_WITH_COLUMN_CHANGE*

the default is true, if the users don't want to update the partition then set it to false
