Examples with HiveParser org.apache.flink.table.planner.delegation.hive.HiveParser used on opensource projects

Example 1 with HiveParser

use of org.apache.flink.table.planner.delegation.hive.HiveParser in project flink by apache.

the class HiveDialectITCase method testParseCommand.

@Test
public void testParseCommand() {
    TableEnvironmentInternal tableEnvInternal = (TableEnvironmentInternal) tableEnv;
    Parser parser = tableEnvInternal.getParser();
    // hive dialect should use HiveParser
    assertTrue(parser instanceof HiveParser);
    assertThat(parser.parse("HELP").get(0), instanceOf(HelpOperation.class));
    assertThat(parser.parse("clear").get(0), instanceOf(ClearOperation.class));
    assertThat(parser.parse("SET").get(0), instanceOf(SetOperation.class));
    assertThat(parser.parse("ResET").get(0), instanceOf(ResetOperation.class));
    assertThat(parser.parse("Exit").get(0), instanceOf(QuitOperation.class));
}

Example 2 with HiveParser

use of org.apache.flink.table.planner.delegation.hive.HiveParser in project flink by apache.

the class HiveDialectITCase method testPluggableParser.

@Test
public void testPluggableParser() {
    TableEnvironmentInternal tableEnvInternal = (TableEnvironmentInternal) tableEnv;
    Parser parser = tableEnvInternal.getParser();
    // hive dialect should use HiveParser
    assertTrue(parser instanceof HiveParser);
    // execute some sql and verify the parser instance is reused
    tableEnvInternal.executeSql("show databases");
    assertSame(parser, tableEnvInternal.getParser());
    // switching dialect will result in a new parser
    tableEnvInternal.getConfig().setSqlDialect(SqlDialect.DEFAULT);
    assertNotEquals(parser.getClass().getName(), tableEnvInternal.getParser().getClass().getName());
