Interpreters conf & usage!

@doanduyhai

Interpreter processing lifecycle!①  Receive input commands/data •  as raw text

•  from form data

②  Process the input commands/data by the external back-end ③  Format the response using Zeppelin display system ④  Send response back to the Zeppelin engine

@doanduyhai

Core interpreters !!•  Spark (Spark core, SparkSQL/DataFrame, PySpark) •  Spark core = default (or %spark)

•  SparkSQL = %sql

•  Shell (%sh)

•  Markdown (%md) !

•  AngularJS (%angular)

@doanduyhai

Third-parties interpreters!•  Hive •  Phoenix •  Tajo •  Flink •  Ignite •  Lens •  Cassandra •  Geode •  PostgreSQL •  Kylin

Writing An Interpreter !!

How To!Simple interpreter example (AsciiDoc)!

Complex interpreter example (Cassandra)!

@doanduyhai

Steps to write your own interpreter!

•  Create a class that extends Interpreter base class

•  Register it in a static block

•  Optionnally define default config params

18

static { Interpreter.register("MyInterpreterName", MyClassName.class.getName());

}

static { Interpreter.register("MyInterpreterName", MyClassName.class.getName(), new InterpreterPropertyBuilder() .add("property1", "default value", "Description of property1").build());

}

@doanduyhai

To register your interpreter as default !

•  Edit the enum ZeppelinConfiguration.ConfVars

•  Add your interpreter FQCN in the property ZEPPELIN_INTERPRETERS

19

@doanduyhai

To register your interpreter in config files!

•  Create conf/zeppelin-site.xml from conf/zeppelin-site.xml.template

•  Add your interpreter FQCN in the property zeppelin.interpreters

Zeppelin future!!

Roadmap!

@doanduyhai

Roadmap & future!•  More graph options (Map viz ZEPPELIN-157)

•  Helium project, packaging Zeppelin view, logic (code) & resource into Applications

•  Interpreters packaging re-design •  ship & compile core interpreters only

•  third-parties interpreters can be pulled from repository

•  which interpreter is core ? Who will maintain ? Community….

•  Integrate security (Apache Shiro, ZEPPELIN-53 )

27

@doanduyhai

Roadmap & future!•  Out of incubation state to become 1st class Apache project
