> Currently when we create / rename a managed table, we should get the defaultTablePath for them in ExternalCatalog, then we have two defaultTablePath logic in its two subclass HiveExternalCatalog and InMemoryCatalog, additionally there is also a defaultTablePath in SessionCatalog, so till now we have three defaultTablePath in three classes. 
> we'd better to unify them up to SessionCatalog
> To unify them, we should move some logic from ExternalCatalog to SessionCatalog, renameTable is one of this.
> while limit to the simple parameters in renameTable 
> {code}
>   def renameTable(db: String, oldName: String, newName: String): Unit
> {code}
> even if we move the defaultTablePath logic to SessionCatalog, we can not pass it to renameTable.
> So we can add a newTablePath parameter  for renameTable in ExternalCatalog
