   > @zhedoubushishi we already have a hudi.properties file. Can you please elaborate the use case for this PR once?
   
   Sorry for the late reply. This is not the same as ```hudi.properties```. ```hudi.properties``` is created when customers write a Hudi table and it's a table level configuration. 
   
   However, the external configuration file in this PR is not specific to any Hudi table. It's more like a cluster level configuration just like ```spark-defaults.conf``` in Spark and ```flink-conf. yaml``` in Flink. The benefit of having this external configuration file, is there are some configurations can be shared between different Hudi tables, e.g. Hive JDBC URL, Zookeeper connect URL, HBase URL...
