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。
- 在本地创建zip文件
hzlishuming@hadoop691:~/env/spark$ cd jars/
hzlishuming@hadoop691:~/env/spark$ zip spark2.1.1-hadoop2.7.3.zip ./*
- 上传至HDFS并更改权限
hzlishuming@hadoop691:~/env/spark$ /usr/ndp/current/hdfs_client/bin/hdfs dfs -mkdir /tmp/spark-archive
hzlishuming@hadoop691:~/env/spark$ /usr/ndp/current/hdfs_client/bin/hdfs dfs -put ./spark2.1.1-hadoop2.7.3.zip /tmp/spark-archive
hzlishuming@hadoop691:~/env/spark$ /usr/ndp/current/hdfs_client/bin/hdfs dfs -chmod 775 /tmp/spark-archive/spark2.1.1-hadoop2.7.3.zip
3.配置spark-defaut.conf
spark.yarn.archive hdfs:///tmp/spark-archive/spark2.1.1-hadoop2.7.3.zip
可以参考日志如下：
