spark.yarn.jars的配置

1.原因:

官方文档
http://spark.apache.org/docs/latest/running-on-yarn.html#preparations

To make Spark runtime jars accessible from YARN side, you can specify spark.yarn.archive or spark.yarn.jars. For details please refer to Spark Properties. If neither spark.yarn.archive nor spark.yarn.jars is specified, Spark will create a zip file with all jars under $SPARK_HOME/jars and upload it to the distributed cache

设置

将spark/jars下的jar上传到hdfs中

#创建目录
[hadoop@hadoop001 jars]$ hadoop fs -mkdir -p /spark-yarn/jars/
#上传jar
[hadoop@hadoop001 jars]$ hadoop fs -put *.jar /spark-yarn/jars/
#配置目录 spark-defaults.conf 添加
[hadoop@hadoop001 conf]$ vi spark-defaults.confspark.yarn.jars                    hdfs://hadoop001:9000/spark-yarn/jars/*.jar
