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

             Summary: 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: 2.2.0, 2.0.0
            Reporter: Sukumaar Mane


Unable to run a simple test case for EmbeddedKafkaCluster.
 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();
        }
    }

    @Test
    public void thisIsFirstFakeTest() {
        assert true;
    }
}
{code}
But getting these error message at the time of cleanup
{code:java}
java.nio.file.FileSystemException: C:\Users\Sukumaar\AppData\Local\Temp\kafka-3445189010908127083\version-2\log.1: The process cannot access the file because it is being used by another process.
