-------------------------------
Summary: Fix warning: TEMPORARY TABLE ... USING ... is deprecated
and use TempViewAlreadyExistsException when create temp view
Key: SPARK-23035
URL: https://issues.apache.org/jira/browse/SPARK-23035
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.1
Reporter: xubo245
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")
{code:java}
02:11:38.136 WARN org.apache.spark.sql.execution.SparkSqlAstBuilder: CREATE
TEMPORARY TABLE ... USING ... is deprecated, please use CREATE TEMPORARY VIEW
... USING ... instead
{code}
other test cases also have this warning
Another 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.
{code:java}
/**
* 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)
}
{code}
