Russell Alexander Spitzer commented on SPARK-10104:
---------------------------------------------------
Previously with Seq[String] it was possible to extend the data within a
TableIdentifier. This was used to allow the specification of a "Cluster",
"Database" and Table. This made it possible for us segregate identifiers based
on what cluster they were being read from.
Currently we are trying to determine a workaround to store extra information in
the TableIdentifier. [~alexliu68]
> Consolidate different forms of table identifiers

> Key: SPARK-10104
> URL: https://issues.apache.org/jira/browse/SPARK-10104
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Yin Huai
> Assignee: Wenchen Fan
> Fix For: 1.6.0
>
>
> Right now, we have QualifiedTableName, TableIdentifier, and Seq[String] to
> represent table identifiers. We should only have one form and looks
> TableIdentifier is the best one because it provides methods to get table
> name, database name, return unquoted string, and return quoted string.
> There will be TODOs having "SPARK-10104" in it. Those places need to be
> updated.
