------------------------------------
This issue is still present in 2.3.0
> Error while cleanup under windows for EmbeddedKafkaCluster
> ----------------------------------------------------------
>
> Key: KAFKA-8427
> URL: https://issues.apache.org/jira/browse/KAFKA-8427
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.0.0, 2.2.0
> Reporter: Sukumaar Mane
> Priority: Major
> Labels: kafka, testing, win10, windows
>
> Unable to run a simple test case for EmbeddedKafkaCluster where there is an
> object of EmbeddedKafkaCluster with 1 broker.
> Running below simple code (which is actually code snippet from
> *org.apache.kafka.streams.KafkaStreamsTest* class)
> {code:java}
> public class KTest {
> private static final int NUM_BROKERS = 1;
> // We need this to avoid the KafkaConsumer hanging on poll
> // (this may occur if the test doesn't complete quickly enough)
> @ClassRule
> public static final EmbeddedKafkaCluster CLUSTER = new
> EmbeddedKafkaCluster(NUM_BROKERS);
> private static final int NUM_THREADS = 2;
> private final StreamsBuilder builder = new StreamsBuilder();
> @Rule
> public TestName testName = new TestName();
> private KafkaStreams globalStreams;
> private Properties props;
> @Before
> public void before() {
> props = new Properties();
> props.put(StreamsConfig.APPLICATION_ID_CONFIG, "appId");
> props.put(StreamsConfig.CLIENT_ID_CONFIG, "clientId");
> props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG,
> CLUSTER.bootstrapServers());
> props.put(StreamsConfig.METRIC_REPORTER_CLASSES_CONFIG,
> MockMetricsReporter.class.getName());
> props.put(StreamsConfig.STATE_DIR_CONFIG,
> TestUtils.tempDirectory().getPath());
> props.put(StreamsConfig.NUM_STREAM_THREADS_CONFIG, NUM_THREADS);
> globalStreams = new KafkaStreams(builder.build(), props);
> }
> @After
> public void cleanup() {
> if (globalStreams != null) {
> globalStreams.close();
> }
