------------------------------------

             Summary: SQL client does not support views that reference a table from DDL
                 Key: FLINK-17190
                 URL: https://issues.apache.org/jira/browse/FLINK-17190
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Client
            Reporter: Timo Walther


It seems to be a classloading issue when the view references a DDL table.

{code}
CREATE TABLE PROD_LINEITEM (
  L_ORDERKEY       INTEGER,
  L_PARTKEY        INTEGER,
  L_SUPPKEY        INTEGER,
  L_LINENUMBER     INTEGER,
  L_QUANTITY       DOUBLE,
  L_EXTENDEDPRICE  DOUBLE,
  L_DISCOUNT       DOUBLE,
  L_TAX            DOUBLE,
  L_CURRENCY       STRING,
  L_RETURNFLAG     STRING,
  L_LINESTATUS     STRING,
  L_ORDERTIME      TIMESTAMP(3),
  L_SHIPINSTRUCT   STRING,
  L_SHIPMODE       STRING,
  L_COMMENT        STRING,
  WATERMARK FOR L_ORDERTIME AS L_ORDERTIME - INTERVAL '5' MINUTE,
  L_PROCTIME       AS PROCTIME()
) WITH (
  'connector.type' = 'kafka',
  'connector.version' = 'universal',
  'connector.topic' = 'Lineitem',
  'connector.properties.zookeeper.connect' = 'not-needed',
  'connector.properties.bootstrap.servers' = 'kafka:9092',
  'connector.startup-mode' = 'earliest-offset',
  'format.type' = 'csv',
  'format.field-delimiter' = '|'
);

CREATE VIEW v AS SELECT * FROM PROD_LINEITEM;
{code}

Result:
{code}

Caused by: org.apache.flink.table.api.NoMatchingTableFactoryException: Could not find a suitable table factory for 'org.apache.flink.table.factories.TableSourceFactory' in
the classpath.

Reason: Required context properties mismatch.

The matching candidates:
org.apache.flink.table.sources.CsvBatchTableSourceFactory
Mismatched properties:
'connector.type' expects 'filesystem', but is 'kafka'

....

The following factories have been considered:
org.apache.flink.table.sources.CsvBatchTableSourceFactory
org.apache.flink.table.sources.CsvAppendTableSourceFactory
