资源说明:The success of Hadoop as a big data platform raised user expectations, both in terms of 
solving different analytics challenges as well as reducing latency. Various tools evolved over 
time, but when Apache Spark came, it provided one single runtime to address all these 
challenges. It eliminated the need to combine multiple tools with their own challenges and 
learning curves. By using memory for persistent storage besides compute, Apache Spark 
eliminates the need to store intermedia data in disk and increases processing speed up to 
100 times. It also provides a single runtime, which addresses various analytics needs such  
as machine-learning and real-time streaming using various libraries.
This book covers the installation and configuration of Apache Spark and building solutions 
using Spark Core, Spark SQL, Spark Streaming, MLlib, and GraphX libraries.
