我一直想逃跑 spark-shell
Yarn client
但是我得到了很多 ClosedChannelException
错误。我正在为Hadoop2.6使用Spark2.0.0版本。
例外情况如下:
$ spark-2.0.0-bin-hadoop2.6/bin/spark-shell --master yarn --deploy-mode client
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel).

我已经建立了另一个答案,这取决于您使用的是spark客户端还是集群模式。
在集群模式下,当我指定驱动程序内存——驱动程序内存为512m时,它失败了(默认设置请求2gb的am资源(这包括驱动程序内存+为应用程序主机请求的开销),这就足够了)
在客户机模式下,重要的设置是spark.yarn.am.memory,因为默认情况下,am只需要1024m,这太少了,因为java 8需要大量的虚拟内存。>10万2千4百万似乎在起作用。
答案在这里描述

我个人通过增加
yarn.nodemanager.vmem-pmem-ratio
正如akira ajisaka在jira票中所建议的:2lpgd9683#
我收到了ClosedChannel异常,但有一条不同的消息:
在mappartition中,我对记录进行批处理,并进行http调用来处理这些记录,这可能需要几分钟的时间。可能是spark假设分区死了,因为它在很长一段时间内没有获取更多的记录,因此我们得到了这个异常。
用更长的值设置网络超时。

原因是,由于java 8内存分配过多的问题,可能会丢失与yarn cluster的关联:https://issues.apache.org/jira/browse/yarn-4714
通过在yarn-site.xml中设置以下属性,可以强制yarn忽略此问题
多亏了simplejack,来自spark-pi示例的参考资料在带有yarn的集群模式下:关联丢失
