Question

我是Amazon Kinesis的新手。我已经阅读了基本文档和Kinesis APi以开始使用Kinesis。所以我在scala中编写了一小段代码来创建一个流。但我面临一个例外，如下所示

线程中的异常＆＃34; main＆＃34; java.lang.NoSuchMethodError：org.joda.time.format.DateTimeFormatter.withZoneUTC（）Lorg / joda / time / format / DateTimeFormatter; 在com.amazonaws.auth.AWS4Signer。（AWS4Signer.java:44） at sun.reflect.NativeConstructorAccessorImpl.newInstance0（Native Method） at sun.reflect.NativeConstructorAccessorImpl.newInstance（NativeConstructorAccessorImpl.java:57） at sun.reflect.DelegatingConstructorAccessorImpl.newInstance（DelegatingConstructorAccessorImpl.java:45） at java.lang.reflect.Constructor.newInstance（Constructor.java:526）在java.lang.Class.newInstance（Class.java:379）在com.amazonaws.auth.SignerFactory.createSigner（SignerFactory.java:119）在com.amazonaws.auth.SignerFactory.lookupAndCreateSigner（SignerFactory.java:105）在com.amazonaws.auth.SignerFactory.getSigner（SignerFactory.java:78）在com.amazonaws.AmazonWebServiceClient.computeSignerByServiceRegion（AmazonWebServiceClient.java:307）在com.amazonaws.AmazonWebServiceClient.computeSignerByURI（AmazonWebServiceClient.java:280）在com.amazonaws.AmazonWebServiceClient.setEndpoint（AmazonWebServiceClient.java:160）在com.amazonaws.services.kinesis.AmazonKinesisClient.setEndpoint（AmazonKinesisClient.java:2102）在com.amazonaws.services.kinesis.AmazonKinesisClient.init（AmazonKinesisClient.java:216）在com.amazonaws.services.kinesis.AmazonKinesisClient。（AmazonKinesisClient.java:139）在com.amazonaws.services.kinesis.AmazonKinesisClient。（AmazonKinesisClient.java:116）在com.platalytics.platform.connectors.Kinesis.App $ .create（App.scala：32）在com.platalytics.platform.connectors.Kinesis.App $ .main（App.scala：26）在com.platalytics.platform.connectors.Kinesis.App.main（App.scala） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:57） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.lang.reflect.Method.invoke（Method.java:606）

这是我的代码

def main(args: Array[String]) {
        println("Stream creation started")
        if(create(2))
            println("Stream is created successfully")
    }
    def create(shardCount: Int): Boolean = {
        val credentials = new BasicAWSCredentials(KinesisProperties.AWS_ACCESS_KEY_ID, KinesisProperties.AWS_SECRET_KEY)

        var kinesisClient: AmazonKinesisClient = new AmazonKinesisClient(credentials)
        kinesisClient.setEndpoint(KinesisProperties.KINESIS_ENDPOINT_URL,
            KinesisProperties.KINESIS_SERVICE_NAME,
            KinesisProperties.KINESIS_REGION_ID)
        val createStreamRequest = new CreateStreamRequest()
        createStreamRequest.setStreamName(KinesisProperties.myStreamName);
        createStreamRequest.setShardCount(shardCount)
        val describeStreamRequest = new DescribeStreamRequest()
        describeStreamRequest.setStreamName(KinesisProperties.myStreamName)
        try {
            Thread.sleep(120000)
        } catch {
            case e: Exception =>
        }
        var streamStatus = "not active"
        while (!streamStatus.equalsIgnoreCase("ACTIVE")) {
            try {
                Thread.sleep(1000)
            } catch {
                case e: Exception => e.printStackTrace()
            }
            try {
                val describeStreamResponse = kinesisClient.describeStream(describeStreamRequest)
                streamStatus = describeStreamResponse.getStreamDescription.getStreamStatus
            } catch {
                case e: Exception => e.printStackTrace()
            }
        }
        if (streamStatus.equalsIgnoreCase("ACTIVE"))
            true
        else
            false
    }

这是我在pom文件中的依赖项

            <groupId>joda-time</groupId>
            <artifactId>joda-time</artifactId>
            <version>2.6</version>

各位好友我通过将joda-time jar文件添加到HADOOP_CLASSPATH找到了解决此问题的方法。现在它正在工作
