      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
