@rxin This is an API change. After this PR, the following APIs will accept
the qualified table/function names.
- def listColumns(tableName: String): Dataset[Column]
- def getTable(tableName: String): Table
- def getFunction(functionName: String): Function
- def tableExists(tableName: String): Boolean
- def functionExists(functionName: String): Boolean
Before this PR, `listColumns("db1.tab")` will search a table having the
name `db1.tab`. After this PR, it will search the table having the name `tab`
in the database `db1`
