> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Song Jun
>
> 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
