Spark作业抛出错误（spark节点心跳错误）

Question

我使用 Spark 2.0 和 2 个节点集群（Windows 机器和禁用的防火墙）。我正在运行套接字程序，收到以下错误：

16/10/12 12:10:41 WARN NettyRpcEndpointRef: Error sending message [message = Heartbeat(2,[Lscala.Tuple2;@1ee84de,BlockManagerId(2, IP1, 2726))] in 1 attempts

我已将值

spark.executor.heartbeatInterval

设置为 30。但我仍然收到错误。

我的环境：

服务器1： 我将通过

spark-class org.apache.spark.deploy.master.Master

开始掌握大师 我将在

spark-class org.apache.spark.deploy.worker.Worker spark://server1:7077

之前启动工人

服务器2（ip2）： 我将在

spark-class org.apache.spark.deploy.worker.Worker spark://172.16.2.95:7077

之前启动工人

驱动程序位于服务器 1 中：

spark-submit --master spark://server1:7077  --num-executors 2  --executor-cores 1  C:\sparkpoc\streamexample.py

节点：

有人可以帮助我吗？

Answer 1

该错误消息表明执行器未能在预期的时间范围内向驱动器发送心跳消息。超时由

spark.executor.heartbeatInterval

配置参数控制。

要解决此错误，您可以尝试将

spark.executor.heartbeatInterval

的值增加到比当前值更高的值。您可以在 Spark 配置文件中设置此配置参数，也可以在启动 Spark 应用程序时将其作为命令行参数传递。 spark.executor.heartbeatInterval 60s
