Abstract The recent wave of sensor-rich, Internet-enabled, smart mobile devices such as the Apple iPhone has opened the door for a novel paradigm for monitoring the urban landscape known as participatory sensing. Using this paradigm, ordinary citizens can collect multi-modal data streams from the surrounding environment using their mobile devices and share the same using existing communication infrastructure (e.g., 3G service or WiFi access points). Mobile phones, though not built specifically for sensing, can in fact be used as sensors. The mobile phone camera can be used as a video and image sensor. The microphone on the mobile phone, when not being used for voice conversations, can be doubled up as an acoustic sensor. The embedded GPS receiver can provide location information. Further, other embedded sensors such as gyroscopes, accelerometers and proximity sensors can collectively be used to estimate useful contextual information (e.g., is the user walking or travelling on a bicycle). The data contributed from multiple participants can be combined to build a spatiotemporal view of the phenomenon of interest and also to extract important community statistics. Given the ubiquity of mobile phones and the high density of people in metropolitan areas, participatory sensing can achieve an unprecedented level of coverage in both space and time for observing events of interest in urban spaces. Several exciting participatory sensing applications have emerged in recent years. For example, GPS traces uploaded by drivers and passengers can be used to generate real- time traffic statistics. Similarly, street-level audio samples collected by pedestrians can be aggregated to create a citywide noise map. This revolutionary paradigm is also being used to collect and share data about air pollution, cyclist experiences, diet and pricing information of consumer goods.

Tutors:  

• Basant Verma: Grid Solutions Lead, Grid Solutions, Yahoo!

• Viraj Bhat: Grid Engineer, Grid Solutions, Yahoo Sunnyvale

• Amar Kamat: Hadoop Engineer, Hadoop Engineering

Abstract Apache Hadoop has become the platform of choice for developing large-scale data-intensive applications. In this tutorial, we will discuss Hadoop concepts, how to develop scalable applications to crunch several terabytes of data using Hadoop and higher-level frameworks such as Pig/Hive. We will also discuss design patterns and solutions to common problems encountered in achieving optimal performance from Hadoop application.

Biographies of tutor: 

Basant Verma is leading Grid Solutions team at Yahoo Bangalore, where he is working with Yahoo users in building Hadoop/Pig based data-intensive applications running on Yahoo! Grids.

Viraj Bhat is employed with Yahoo! Sunnyvale as a Senior Grid engineer, where he works on building, porting and parallelizing several data-intensive applications on Yahoo! Grids based on Hadoop (Map Reduce Programming Paradigm). He built Hadoop Vaidya, a performance diagnostic tool for Map/Reduce jobs. He also works on various open source projects such as Pig & Hive for analyzing large datasets.

Amar Kamat is working as part of Hadoop core Engineering group at Bangalore. He has worked in the development of Hadoop M/R framework. Currently he is working on Hadoop performance and Benchmarking framework
