the class HiveCatalogGenericMetadataTest method testFunctionCompatibility.

@Test
public void testFunctionCompatibility() throws Exception {
    catalog.createDatabase(db1, createDb(), false);
    // create a function with old prefix 'flink:' and make sure we can properly retrieve it
    ((HiveCatalog) catalog).client.createFunction(new Function(path1.getObjectName().toLowerCase(), path1.getDatabaseName(), "flink:class.name", null, PrincipalType.GROUP, (int) (System.currentTimeMillis() / 1000), FunctionType.JAVA, new ArrayList<>()));
    CatalogFunction catalogFunction = catalog.getFunction(path1);
    assertEquals("class.name", catalogFunction.getClassName());
    assertEquals(FunctionLanguage.JAVA, catalogFunction.getFunctionLanguage());
}

Example 2 with CatalogFunction

use of org.apache.flink.table.catalog.CatalogFunction in project flink by apache.

    try {
        CatalogFunction function = alterCatalogFunctionOperation.getCatalogFunction();
        if (alterCatalogFunctionOperation.isTemporary()) {

        } else {
            Catalog catalog = getCatalogOrThrowException(alterCatalogFunctionOperation.getFunctionIdentifier().getCatalogName());
            catalog.alterFunction(alterCatalogFunctionOperation.getFunctionIdentifier().toObjectPath(), function, alterCatalogFunctionOperation.isIfExists());
        }
        return TableResultImpl.TABLE_RESULT_OK;
    } catch (ValidationException e) {
        throw e;
    } catch (FunctionNotExistException e) {
        throw new ValidationException(e.getMessage(), e);
    } catch (Exception e) {
        throw new TableException(exMsg, e);
    }
}

Example 4 with CatalogFunction

use of org.apache.flink.table.catalog.CatalogFunction in project flink by apache.

the class SqlToOperationConverter method convertCreateFunction.

/**
 * Convert CREATE FUNCTION statement.
 */
private Operation convertCreateFunction(SqlCreateFunction sqlCreateFunction) {
    UnresolvedIdentifier unresolvedIdentifier = UnresolvedIdentifier.of(sqlCreateFunction.getFunctionIdentifier());
    if (sqlCreateFunction.isSystemFunction()) {

        return new CreateCatalogFunctionOperation(identifier, catalogFunction, sqlCreateFunction.isIfNotExists(), sqlCreateFunction.isTemporary());
    }
}

Example 5 with CatalogFunction

use of org.apache.flink.table.catalog.CatalogFunction in project flink by apache.
