some basic questions

Hi All,

1) The Documentation says full outer join is supported however the below
code just exits with value 1. No error message.

import org.apache.flink.api.common.serialization.SimpleStringSchema;
import org.apache.flink.streaming.api.datastream.DataStream;
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer;
import org.apache.flink.table.api.*;
import org.apache.flink.table.api.java.StreamTableEnvironment;
import org.apache.flink.types.Row;

import java.util.Properties;

public class Test {

    public static void main(String... args) throws Exception {

        EnvironmentSettings bsSettings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
        final StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
        StreamTableEnvironment bsTableEnv =
StreamTableEnvironment.create(env, bsSettings);

        Properties properties = new Properties();
        properties.setProperty("bootstrap.servers", "localhost:9092");
        properties.setProperty("group.id", "test");

        FlinkKafkaConsumer<String> consumer1 = new FlinkKafkaConsumer<>(
                java.util.regex.Pattern.compile("test-topic1"),
                new SimpleStringSchema(),
                properties);
        FlinkKafkaConsumer<String> consumer2 = new FlinkKafkaConsumer<>(
                java.util.regex.Pattern.compile("test-topic2"),
                new SimpleStringSchema(),
                properties);

        DataStream<String> stream1 = env.addSource(consumer1);
        DataStream<String> stream2 = env.addSource(consumer2);

        bsTableEnv.registerDataStream("sample1", stream1);
        bsTableEnv.registerDataStream("sample2", stream2);

        Table result = bsTableEnv.sqlQuery("SELECT * FROM sample1 FULL
OUTER JOIN sample2 on sample1.f0=sample2.f0");
        result.printSchema();

        bsTableEnv.toAppendStream(result, Row.class).print();
        bsTableEnv.execute("sample job");
    }
}


2) If I am using a blink planner should I use TableEnvironment or
StreamTableEnvironment ?

3) Why flink current stable documentation(1.9) recommends (old planner)?
any rough timeline on when we would be able to use blink planner in
production? perhaps 1.10 or 1.11?

Thanks!
