1.日志采集

1. 分布式，集群
   3.zookeeper，docker，linux

4.机器学习，是建模和算法
5.tensrflow,jupyter
6.日志采集flume,kafka
7.机器学习kaggle，---deep learning 神经网络，图像识别
8.人工智能----包括----机器学习----包括deep learning
9.hadoop本质，跑批量数据--block 128M，小文件用oss。强调并行，不是并发
10.mib，sprak中使用python ---爬虫算法，
11.hadoop--仅批处理，storm仅流处理，spark混合

swagger ui 没有正式发布，需要获取的话，指定官方snap仓库

解决方案：把kotlin编译插件放在java编译插件的上面，另外需要kotlin在<phase>process-sources</phase> 阶段就执行
配置如下

<plugins>
