1.为什么要让运行时Jar可以从yarn端访问spark2以后,原有lib目录下的大JAR包被分散成多个小JAR包,原来的spark-assembly-*.jar已经不存在 每一次我们运行的时候,如果没有指定 spark.yarn.archive or spark.yarn.jars Spark将在安装路径下的Jar目录,将其所有的Jar包打包然后将其上传到分布式缓存(官网上的原话是:To make Spark runtime jars accessible from YARN side, yo
1.执行Spark运行在yarn上的命令报错 spark-shell --master yarn-client,错误如下所示: // :: ERROR SparkContext: Error initializing SparkContext. org.apache.spark.SparkException: Yarn application has already ended! It might have been killed or unable to launch application
在Hadoop 2.7.2集群下执行如下命令: spark-shell --master yarn --deploy-mode client 爆出下面的错误: org.apache.spark.SparkException: Yarn application has already ended! It might have been killed or unable to launch application master. 在Yarn WebUI上面查看启动的Cluster状态,log显示为
./bin/spark-shell --master yarn 2019-07-01 12:20:13 WARN NativeCodeLoader:62 - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Setting default log level to "WARN". To adjust logging level use
spark通過idea远程提交job到yarn: Caused by: java.lang.ClassCastException: cannot assign instance of scala.collection.immutable.List$SerializationProxy to field org.apache.spark.rdd.RDD.org$apache$spark$rdd$RDD$$dependencies_ of type scala.collection.Seq in i
报错如下 18/06/06 15:55:31 ERROR cluster.YarnClientSchedulerBackend: Yarn application has already exited with state FINISHED! 18/06/06 15:55:31 ERROR client.TransportClient: Failed to send RPC 8494797597505892687 to /192.168.1.21:44578: java.nio.channels
继上次的Spark-shell脚本源码分析,还剩下后面半段.由于上次涉及了不少shell的基本内容,因此就把trap和stty放在这篇来讲述. 上篇回顾:Spark源码分析之Spark Shell(上) function main() { if $cygwin; then # Workaround for issue involving JLine and Cygwin # (see http://sourceforge.net/p/jline/bugs/40/). # If you're us
