Couchbase&x2B；Scala+；Java SDK:IndexOutOfBounds

我对scala和couchbase都比较陌生，但我需要快速学习。最近，在尝试通过Scala使用Java couchbase SDK运行示例应用程序时，我遇到了以下问题

[cb-core-3-2] WARN com.couchbase.client.core.CouchbaseCore - Exception while Handling Request Events RequestEvent{request=null}

这就是产生错误的代码

import com.couchbase.client.java.document._
import com.couchbase.client.java.document.json._

object App {
  def main(args: Array[String]): Unit = {
    // Initialize the Connection
    // Connects to localhost
    val env = DefaultCouchbaseEnvironment.builder()
  .connectTimeout(5000)
  .bootstrapCarrierEnabled(false)
  .build()

val cluster = CouchbaseCluster.create(env, "127.0.0.1")
// Opens the "default" bucket
val bucket = cluster.openBucket("default")

// Create a JSON Document
val user: JsonObject = JsonObject.create()
  .put("firstname", "Walter")
  .put("lastname", "White")
  .put("job", "chemistry teacher")
  .put("age", 50)

 val stored: JsonDocument = bucket.upsert(JsonDocument.create("walter", user));

// Load the Document and print it
// Prints Content and Metadata of the stored Document
println(bucket.get("walter"))

// Just close a single bucket
bucket.close();

// Disconnect and close all buckets
cluster.disconnect();
}
}

我对此有点陌生，但以下是我从调试器中获得的信息

编辑2:

我看了一下Couchbase控制台日志，不断得到以下信息

Service 'memcached' exited with status 1. Restarting. Messages: Failed to open library "/Users/luishreis/Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/lib/memcached/stdin_term_handler.so": dlopen(/Users/luishreis/Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/lib/memcached/stdin_term_handler.dylib, 6): image not found

在此问题上如有任何帮助，将不胜感激

非常感谢。

这很奇怪，它似乎表明1）SDK对vBucket的密钥进行了哈希运算，该vBucket太大（1894而不是1024），2）集群映射为空。能否尝试在异常上设置断点，并查看

nodeIndexForMaster

中使用了哪些参数？（值得注意的是

useFastForward

）@SimonBasléI用您要求的信息更新了问题，尽管我不确定这是否是您要求的信息。我在couchbase jdk中该函数的返回语句上放置了一个断点。现在您也提到了它，IndexOutOfBounds错误会定期抛出一个不同的索引。通常是

java.lang.IndexOutOfBoundsException:Index:7620，Size:0

您的couchbase安装似乎有问题。。。我会尝试一次完全的重新安装，这很奇怪，它似乎表明1）SDK散列了一个vBucket的密钥，这个vBucket太大了（1894而不是1024），2）集群映射是空的。能否尝试在异常上设置断点，并查看
