Question

我的Spark工作失败并出现以下异常，我无法找出导致失败的要求缺失：

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

Spark-submit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

同一程序与master作为本地程序可以正常工作。

任何建议都会有很大的帮助。提前谢谢。

我在classpath中有一个巨大的罐子列表，使用＆＃39; - jars＆＃39;元素和罐子之一是罪魁祸首，当我从＆＃39; - jars＆＃39;问题得到解决，我仍然不确定为什么spark-submit因为那个jar而失败。

我遇到了由数据文件引起的错误。我指向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

我修正了train数据源方向，问题解决了。

我收到了类似的错误：

解决方法是：

在终端或日志上，您将有一条WARN行，如下所示：

WARN客户端：资源文件：多次添加到分布式缓存中。

只需从spark提交脚本中删除这个额外的jar。希望这对所有人都有帮助。

使用纱线主控器时，Spark-submit失败，scala.Predef中的错误要求失败
