XixiHua updated HUDI-4396:
--------------------------
Description:
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
