advocate •  talks, meetups, confs •  open-source devs (Achilles, …) •  OSS Cassandra point of contact ☞ [email protected] ☞ @doanduyhai 2

@doanduyhai Datastax •  Founded in April 2010 •  We contribute
a lot to Apache Cassandra™ •  400+ customers (25 of the Fortune 100), 400+ employees •  Headquarter in San Francisco Bay area •  EU headquarter in London, ofﬁces in France and Germany •  Datastax Enterprise = OSS Cassandra + extra features 3

@doanduyhai What does Zeppelin provide ? Front-end & display system

@doanduyhai Zeppelin Display System •  Raw, Table, HTML, AngularJS with
Scala •  Graphs •  Dynamic Forms •  View modes •  Export as Iframe

@doanduyhai Interpreter System •  Core interpreters •  Third-party interpreters • 
Interpreter 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 17

@doanduyhai Core interpreters •  Spark (Spark core, SparkSQL/DataFrame, PySpark) • 
Spark core = default (or %spark) •  SparkSQL = %sql •  Shell (%sh) •  Markdown (%md) •  AngularJS (%angular) 18

@doanduyhai Third-parties interpreters •  Hive •  Phoenix •  Tajo • 
Flink •  Ignite •  Lens •  Cassandra •  Geode •  PostgreSQL •  Kylin •  ElasticSearch 19

@doanduyhai Writing an interpreter •  How To •  Simple interpreter
(AsciiDoc) •  Complex interpreter (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 22 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 23

@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 24 <property> <name>zeppelin.interpreters</name> <value>org.apache.zeppelin.spark.SparkInterpreter,org.apache.zeppelin.spark.PySparkInterpreter, org.apache.zeppelin.spark.SparkSqlInterpreter,org.apache.zeppelin.spark.DepInterpreter, org.apache.zeppelin.markdown.Markdown,org.apache.zeppelin.shell.ShellInterpreter, org.apache.zeppelin.hive.HiveInterpreter,com.me.MyNewInterpreter </value> </property>

@doanduyhai Zeppelin Future •  Road Map

@doanduyhai Enterprise Ready •  Apache Shiro authentication (ZEPPELIN-548) •  Note
authorization (PR #681) •  Multi-tenancy 34

@doanduyhai Usability •  UX improvement •  Better table data support
•  Export data as CSV etc . (PR #725, PR #714, PR #6, PR #89) •  Table pagination … 35

@doanduyhai Pluggability •  Pluggable visualization •  Pluggable interpreter •  Repository
and registry for pluggable components 36

@doanduyhai More interpreters 37
