Learning Cloudera Impala – Book Availability

Learning Cloudera Impala:

 

Using Cloudera Impala is for those who really want to take advantage of their Hadoop cluster by processing extremely large amounts of raw data in Hadoop at real-time speed. Prior knowledge of Hadoop and some exposure to HIVE and MapReduce is expected.

 

Learning Cloudera Impala

You will learn from this book:

• Understand the various ways of installing Impala in your Hadoop cluster
• Use the Impala shell API to interact with Impala components
• Utilize Impala Query Language and built-in functions to play with data
• Administrate and fine-tune Impala for high availability
• Identify and troubleshoot problems in a variety of ways
• Get acquainted with various input data formats in Hadoop and how to use them with Impala
• Comprehend how third party applications can connect with Impala to provide data visualization and various other enhancements

Hadoop and Spark Join Forces in Yahoo
Andy Feng (Distinguished Architect, Cloud Services, Yahoo)

YAHOO AT SCALE:

• 150 PB of data on Yahoo Hadoop clusters
  • Yahoo data scientists need the data for
    • Model building
    • BI analytics
  • Such datasets should be accessed efficiently
    • avoid latency caused by data movement
• 35,000 servers in Hadoop cluster
  • Science projects need to leverage all these servers for computation

SOLUTION: HADOOP + SPARK

• science … Spark API & MLlib ease development of ML algorithms
• speed … Spark reduces latency of model training via in-memory RDD etc
• scale … YARN brings Hadoop datasets & servers at scientists’ fingertips

Spark in the Hadoop Ecosystem
Eric Baldeschwieler (@jeric14)

Data scientists & Developers need an open standard for sharing their Algorithms & functions, an “R” for big data. 

• Spark best current candidate:
•  Open Source – Apache Foundation
•  Expressive (MR, iteration, Graphs, SQL, streaming)
•  Easily extended & embedded (DSLs, Java, Python…)

Spark “on the radar”
•  2008 – Yahoo! Hadoop team collaboration w Berkeley Amp/Rad lab begins
•  2009 – Spark example built for Nexus -> Mesos
•  2011 – “Spark is 2 years ahead of anything at Google””- Conviva seeing good results w Spark
•  2012 – Yahoo! working with Spark / Shark
•  Today – Many success stories” – Early commercial support
