Sobre este Curso

Sobre este Curso

Note : This course is built on top of the “Real World Vagrant - Build an Apache Spark Development Env! - Toyin Akin” course. So if you do not have a Spark + ScalaIDE environment already installed (within a VM or directly installed), you can take the stated course above.

Scala IDE provides advanced editing and debugging support for the development of pure Scala and mixed Scala-Java applications. 

Now with a shiny Scala debugger, semantic highlight, more reliable JUnit test finder, an ecosystem of related plugins, and much more.

Scala Debugger. Stepping through closures and Scala-aware display of debugging information.

Spark Monitoring and Instrumentation

While creating RDDs, performing transformations and executing actions, you will be working heavily within the monitoring view of the Web UI.

Every SparkContext launches a web UI, by default on port 4040, that displays useful information about the application. This includes:

A list of scheduler stages and tasks
A summary of RDD sizes and memory usage
Environmental information.
Information about the running executors

_ Why Apache Spark … _

Apache Spark  run programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.  Apache Spark  has an advanced DAG execution engine that supports cyclic data flow and in-memory computing.  Apache Spark  offers over 80 high-level operators that make it easy to build parallel apps. And you can use it interactively from the Scala, Python and R shells.  Apache Spark  can combine SQL, streaming, and complex analytics.

Apache Spark  powers a stack of libraries including SQL and DataFrames, MLlib for machine learning, GraphX, and Spark Streaming. You can combine these libraries seamlessly in the same application.
