Who is using Apache Hadoop

•Traditionally = Developers

•Increasingly = Business Users / Data Scientists

•Why does this matter?

Configuring and managing a Hadoop cluster is hard

4

Resources / Expertise

5

Multiple Performance and Design Variables

6

The Cloud solves some of these

7

Advantages of using the cloud

FastEasy

Flexible

8

You still require expertise

Swift Filesystem for Hadoop: HADOOP-8545•New filesystem URL, swift://•Read from, write to local & remote Swift clusters

•Keep long-lived data in Swift; upload while Hadoop cluster off-line

The challenges of running Map Reduce jobs against Swift..

• Identity management• Block size• Object store vs file

paths• Direct API into swift

from HDFS
