启动Spark任务时，在没有配置spark.yarn.archive或者spark.yarn.jars时， 会看到不停地上传jar非常耗时；使用spark.yarn.archive可以大大地减少任务的启动时间，整个处理过程如下
1.在本地创建zip文件
hzlishuming@hadoop691:~/env/spark$ cd jars/ hzlishuming@hadoop691:~/env/spark/jars$ zip spark2.1.1-hadoop2.7.3.zip ./*
2.上传至HDFS并更改权限
hzlishuming@hadoop691:~/env/spark$ hdfs dfs -mkdir /tmp/spark-archive hzlishuming@hadoop691:~/env/spark$ hdfs dfs -put ./spark2.1.1-hadoop2.7.3.zip /tmp/spark-archive hzlishuming@hadoop691:~/env/spark$ hdfs dfs -chmod 775 /tmp/spark-archive/spark2.1.1-hadoop2.7.3.zip
3.配置spark-defaut.conf
hdfs:///tmp/spark-archive/spark2.1.1-hadoop2.7.3.zip
可以参考日志如下：
