> When we save a table into hive metastore, hive will generate some table properties automatically. e.g. transient_lastDdlTime, last_modified_by, rawDataSize, etc. Some of them are useless in Spark SQL, we should remove them.
> It will be good if we can get the list of Hive-generated table properties via Hive API, so that we don't need to hardcode them.
> We can take a look at Hive code to see how it excludes these auto-generated table properties when describe table.
