--------------------------------
Summary: Decide if we should still support CREATE EXTERNAL TABLE
AS SELECT
Key: SPARK-14507
URL: https://issues.apache.org/jira/browse/SPARK-14507
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Yin Huai
Look like we support CREATE EXTERNAL TABLE AS SELECT by accident. Should we
still support it? Seems Hive does not support it. Based on the doc Impala,
seems Impala supports it. Right now, seems the rule of CreateTables in
HiveMetastoreCatalog.scala does not respect EXTERNAL keyword when
{{hive.convertCTAS}} is true and the CTAS query does not provide any storage
format. For this case, the table will become a MANAGED_TABLE and stored in the
default metastore location (not the user specified location).
