Question

我有一个火花流式传输作业，它从Kafka读取数据并对其进行一些操作。我正在通过一个纱线集群Spark 1.4.1运行这个工作，它有两个节点，每个节点有16 GB RAM，每个节点有16个核心。

我将这些内容传递给了spark-submit工作：

- master yarn-cluster --num-executors 3 --driver-memory 4g --executor-memory 2g --executor-cores 3

作业返回此错误并在运行一段时间后结束：

INFO yarn.ApplicationMaster: Final app status: FAILED, exitCode: 11,
(reason: Max number of executor failures reached)

.....

ERROR scheduler.ReceiverTracker: Deregistered receiver for stream 0:
Stopped by driver

已更新：

也找到了这些日志：

INFO yarn.YarnAllocator: Received 3 containers from YARN, launching executors on 3 of them.....

INFO yarn.ApplicationMaster$AMEndpoint: Driver terminated or disconnected! Shutting down.

....

INFO yarn.YarnAllocator: Received 2 containers from YARN, launching executors on 2 of them.

Container exited with a non-zero exit code 1

这可能是什么原因？感谢一些帮助。

Answer 1

你能告诉你从kafka读取的scala / java代码吗？我怀疑你可能没有正确创建SparkConf。

尝试类似

的内容

SparkConf sparkConf = new SparkConf().setAppName("ApplicationName");

还尝试在yarn-client模式下运行应用程序并共享输出。

我遇到了同样的问题。我找到了一个解决问题的解决方案，删除http://localhost:9080/cron/jobs/函数末尾的sparkContext.stop()，保留GC的main操作。

Spark团队已经在Spark核心中解决了这个问题，但是到目前为止，修复工具刚刚成为了主分支。我们需要等到修复程序更新到新版本。
