Agenda

• Big Data and Ecosystem tools

• Apache Spark

• Apache Zeppelin

• Data Visualization

• Combining Spark and Zeppelin

BIG DATA AND ECOSYSTEM TOOLS

Big Data

• Data size beyond systems capability

– Terabyte, Petabyte, Exabyte

• Storage

– Commodity servers, RAID, SAN

• Processing

– In reasonable response time

– A challenge here

4

Server

Tradition processing tools

• Move what ?

– the data to the code or

– the code to the data

Code

Traditional processing tools

• Traditional tools

– RDBMS, DWH, BI

– High cost

– Difficult to scale beyond certain data size

• price/performance skew

• data variety not supported

6

Map-Reduce and NoSQL

• Hadoop toolset

– Free and open source

– Commodity hardware

– Scales to exabytes(1018), maybe even more

• Not only SQL

– Storage and query processing only

– Complements Hadoop toolset

– Volume, velocity and variety

7

All is well ?

• Hadoop was designed for batch processing

• Disk based processing: slow

• Many tools to enhance Hadoop’s capabilities

– Distributed cache, Haloop, Hive, HBase

• Not for interactive and iterative

8

Technological singularity

• When AI capability exceeds Human capacity

• AI or non-AI singularity

Hadoop and Spark

• Spark complements the Hadoop ecosystem

• Replaces: Hadoop MR

• Spark integrates with

– HDFS

– Hive

– HBase

– YARN

15

Other big data tools

• Spark also integrates with

– Kafka

– ZeroMQ

– Cassandra

– Mesos

16

Programming Spark

• Java

• Scala

• Python

• R

What is Spark for ?

19

Batch

Interactive Streaming

The main difference: speed

• RAM access vs Disk access

– RAM access is 100,000 times faster !

Lambda Architecture pattern

• Used for Lambda architecture implementation

– Batch layer

– Speed layer

– Serving layer

APACHE ZEPPELIN

Interactive data analytics

• For Spark and Flink

• Web front end

• At the back, it connects to

– SQL systems(Eg: Hive)

– Spark

– Flink

Interpreters

Notebook

• Is where you do your data analysis

• Web UI REPL with pluggable interpreters

• Interpreters

– Scala, Python, Angular, SparkSQL, Markdown and Shell

26

User Interface features

• Markdown

• Dynamic HTML generation

• Dynamic chart generation

• Screen sharing via websockets

27

SQL Interpreter

• SQL shell

– Query spark data using SQL queries

– Return normal text, HTML or chart type results

28

Scala interpreter for Spark

• Similar to the Spark shell

• Upload your data into Spark

• Query the data sets(RDDs) in your Spark server

• Execute map-reduce tasks

• Actions on RDD

• Transformations on RDD

%sql select age, count(1) from bank where

marital="${marital=single,single|divorced|married}"

group by age order by age

Zeppelin views: Pie chart from SQL

39

Zeppelin views: Bar chart from SQL

40

Zeppelin views: Angular

41

Share variables: MVVM

• Between Scala/Python/Spark and Angular

• Observe scala variables from angular

42

Scala-Spark Angular

x = “foo” x = “bar”

Zeppelin

Screen sharing using Zeppelin

• Share your graphical reports

– Live sharing

– Get the share URL from zeppelin and share with others

– Uses websockets

• Embed live reports in web pages

43

FUTURE

Spark and Zeppelin

• Spark

– Machine Learning using Spark

– GraphX and MLlib

• Zeppelin

– Additional interpreters

– Better graphics

– Report persistence

– More report templates

– Better angular integration45
