Alex Liu commented on SPARK-4943:
---------------------------------
Should we also change the signatures of Catalog methods to use
{code}tableIdentifier: Seq[String] {code} instead of {code}db: Option[String],
tableName: String{code}?
{code}
def tableExists(db: Option[String], tableName: String): Boolean
def lookupRelation(
databaseName: Option[String],
tableName: String,
alias: Option[String] = None): LogicalPlan
def registerTable(databaseName: Option[String], tableName: String, plan:
LogicalPlan): Unit
def unregisterTable(databaseName: Option[String], tableName: String): Unit
def unregisterAllTables(): Unit
protected def processDatabaseAndTableName(
databaseName: Option[String],
tableName: String): (Option[String], String)
{code}
