Apache spark 为什么要删除Spark执行器（日志中带有“ExecutorAllocationManager:Request to remove ExecutorID”）？

apache-spark pyspark

Apache spark 为什么要删除Spark执行器（日志中带有“ExecutorAllocationManager:Request to remove ExecutorID”）？,apache-spark,pyspark,yarn,Apache Spark,Pyspark,Yarn,我试图在一个由6个c4.2x大型节点组成的AWS集群中执行spark作业，我不知道spark为什么要杀死执行器。。。任何帮助都将不胜感激这里是spark submit命令： . /usr/bin/spark-submit --packages="com.databricks:spark-avro_2.11:3.2.0" --jars RedshiftJDBC42-1.2.1.1001.jar --deploy-mode client --master yarn --num-executors

我试图在一个由6个c4.2x大型节点组成的AWS集群中执行spark作业，我不知道spark为什么要杀死执行器。。。任何帮助都将不胜感激

这里是spark submit命令：

. /usr/bin/spark-submit --packages="com.databricks:spark-avro_2.11:3.2.0" --jars RedshiftJDBC42-1.2.1.1001.jar --deploy-mode client --master yarn --num-executors 12 --executor-cores 3 --executor-memory 7G --driver-memory 7g --py-files dependencies.zip iface_extractions.py 2016-10-01 > output.log

在第行，该行开始删除执行器

17/05/25 14:42:50 INFO ExecutorAllocationManager: Request to remove executorIds: 5, 3

我猜您已经在Spark配置中启用了

Spark提供了一种机制，可以根据工作负载动态调整应用程序占用的资源。这意味着，如果不再使用资源，您的应用程序可能会将资源返还给集群，并在以后有需求时再次请求这些资源。如果多个应用程序共享Spark群集中的资源，此功能尤其有用

默认情况下禁用此功能，并可在所有粗粒度群集管理器上使用，即独立模式、纱线模式和Mesos粗粒度模式

我突出显示了相关部分，该部分表示默认情况下它已禁用，因此我只能猜测它已启用

发件人：

基于工作负载动态分配和删除执行器的代理

话虽如此，我还是要使用web UI，看看是否启用了该属性

使用此功能有两个要求（动态资源分配）。首先，应用程序必须将

spark.dynamicAllocation.enabled

设置为

true

。其次，您必须在同一集群中的每个工作节点上设置外部洗牌服务，并在应用程序中将

spark.shuffle.service.enabled

设置为

true

这是打印信息消息的窗口：

logInfo("Request to remove executorIds: " + executors.mkString(", "))

您还可以使用它杀死执行者，这为Spark开发人员自己杀死执行者提供了一种方法

killExecutors（executorIds:Seq[String]）：布尔值请求群集管理器杀死指定的执行器

实际上有两个

killExecutors

，它们非常有助于演示，因为您可以很容易地演示执行器的来来往往。

为什么不检查

应用程序的纱线日志？在那里，您将了解每个执行者以及他们的AppMaster（其中包含容器_00001）的情况但是问题中显示的命令行包含--num executors 12
，并且应该优先于spark defaults.conf
中定义的任何命令行。我记得关于这一点的一些讨论以及接受--num executors
的更改（以前用于禁用动态分配）。除非我弄错了，纱线的代码是极好的。现在，我又有了另一个证据，证明在每次Spark升级中，您都必须从上到下检查源代码，以发现文档化和未文档化特性中发生了哪些变化=>#JobSecurity
