Zeppelin初体验

Zepplin是一个很有意思的笔记本，支持众多interpreter，包括Flink。在网上找了很多资料，发现直接使用二进制包，或者从源码编译，均无法向Flink 1.7.1提交作业。0.81和0.9.0-SNAPHOST都试过。跟同事咨询了一下，找到一个Zeppelin+Blink的镜像，体验特别好。

$ docker run -d -p 8085:8085 -p 8091:8091 zjffdu/zeppelin-blink:latest

进入Zeppelin控制台：http://localhost:8085，选择Flink Stream Tutorial。先运行Configure Flink Interpreter，初始化好Flink Interpreter。接着运行Register a Stream DataSource to simulate web log，此时Blink集群会启动。Blink控制台：http://localhost:8091/#/overview。

有日志之后就可以运行后面的Stream SQL了。可以看到动态更新的图表。

Zeppelin目前并不支持SQL。如果支持SQL的话，加上Scala，是一个非常好的练手工具。
