Major Description
Problem: it throw TempTableAlreadyExistsException and output "Temporary table '$table' already exists" when we create temp view by using org.apache.spark.sql.catalyst.catalog.GlobalTempViewManager#create, it's improper.
/** * Creates a global temp view, or issue an exception if the view already exists and * `overrideIfExists` is false. */ def create( name: String, viewDefinition: LogicalPlan, overrideIfExists: Boolean): Unit = synchronized { if (!overrideIfExists && viewDefinitions.contains(name)) { throw new TempTableAlreadyExistsException(name) } viewDefinitions.put(name, viewDefinition) }
No need to fix:
warning: TEMPORARY TABLE ... USING ... is deprecated and use TempViewAlreadyExistsException when create temp view
There are warning when run test: test("rename temporary view - destination table with database name")
02:11:38.136 WARN org.apache.spark.sql.execution.SparkSqlAstBuilder: CREATE TEMPORARY TABLE ... USING ... is deprecated, please use CREATE TEMPORARY VIEW ... USING ... instead
other test cases also have this warning
