Spark-submit 使用 yarn master 失败，错误要求在 scala.Predef 失败

Question

我的 Spark 作业因以下异常而失败，我无法弄清楚缺少什么导致作业失败的要求：

Exception in thread "main" java.lang.IllegalArgumentException: requirement failed
        at scala.Predef$.require(Predef.scala:221)
        at org.apache.spark.deploy.yarn.Client$$anonfun$prepareLocalResources$6$$anonfun$apply$3.apply(Client.scala:472)
        at org.apache.spark.deploy.yarn.Client$$anonfun$prepareLocalResources$6$$anonfun$apply$3.apply(Client.scala:470)

        at org.apache.spark.deploy.yarn.Client.run(Client.scala:1021)

        at org.apache.spark.deploy.yarn.Client.main(Client.scala)

        at org.apache.spark.deploy.SparkSubmit$.org$apache$spark$deploy$SparkSubmit$$runMain(SparkSubmit.scala:742)

Spark提交命令：

spark-submit --conf spark.driver.extraJavaOptions=-Dlog4j.configuration=file:/xyz/conf/log4j.xml \
-DHOME=/xyz/transformation -DENV=e1 \
-DJOB=xformation --conf spark.local.dir=/warehouse/tmp/spark1489619325 \
--queue dev --master yarn --deploy-mode cluster \
--properties-file /xyz/conf/job.conf \
--files /xyz/conf/e1.properties --class TransformationJob /xyz/job.jar

相同的程序在 master 和 local 上都可以正常工作。

任何建议都会有很大帮助。 提前致谢。

Answer 1

我在类路径中有大量使用“--jars”元素的 jar 列表，其中一个 jar 是罪魁祸首，当我从“--jars”中删除它时，问题得到了解决，我仍然不确定为什么 spark-submit 失败因为那个罐子。

Answer 2

我有由数据文件引起的错误。 我指出了错误的火车数据方向。

训练数据和测试数据不匹配。

训练数据： 0,1 0 0 1 0 0 1 0 0 1

测试数据： 1, 2, 0, 0, 10

我修复了火车数据源方向，问题已经解决。

我收到了类似的错误：

解决方法是：

在终端或日志上，您将有一个 WARN 行，如下所示：

警告客户端：资源文件：多次添加到分布式缓存中。

只需从 spark submit script 中删除这个额外的 jar。 希望这会帮助所有人。
