What makes Spark so powerful?

Apache spark is the multi-role jet fighter in combat with the colossal loads of Big-Data in Data Analytics. It is capable to deal with almost all types of data irrelevant to its structure and size with lightning speeds. Here are a few reasons for which the Spark is considered the most powerful Big Data tool.

• Integration with Hadoop

Spark can be directly integrated on to Hadoop’s HDFS and work as an excellent Data Processing Tool. Coupled with YARN, It can run on the same cluster along the side of MapReduce Jobs.

• Meet the global Standards

Learning spark has become one of the global standards as there is an impeccable raise in the world of Big Data Analytics with Apache Spark standing by its side.

• Faster than MapReduce

There is a lot of performance gap when it comes to deciding between MapReduce and Spark. The lightning-fast performance due to its In-Memory Processing Capability brought Spark its place amongst the top-level Apache Projects.

• Capable to perform in Production Environment

The simple and faster programming interface of spark can support top-notch programming languages like Scala, Java and Python. This gave a staggering edge to Spark to be the leading legend in the Production Environment with a massive surge in its demand.

• Raising Demand for Spark Developers

Due to its Outperformed Capabilities and reliability, Spark is preferred by many Top MNCs like Adobe, Yahoo, NASA and many more. Proportionately, the demand for Spark Developers is also visualizing a rapid rise.

Introduction to Apache Spark

Apache Spark is the Open-Source software utility by the Apache Foundation. It was designed and deployed as an upgrade to Apache Hadoop’s processing capabilities. unlike the common myth, Apache Spark is never the replacement to Hadoop. It is another processing layer like MapReduce.

Now, the definition. Apache Spark is the lightning-fast cluster computing framework that provides the interface to program the entire cluster so as to achieve implicit data parallelism and fault-tolerance.

Road map to become Apache Spark Developer

There is a thin line of the gap between actually becoming a certified Apache Spark Developer and to be an actual Apache Spark Developer capable enough perform in the real-time application.

• So, to become an expert level Spark Developer you need to follow the right path the expert level guidance from the certified real-time industry experts in the industry. For a beginner, it is the best time to take up a training and certification program.
• Once the Certification has begun, you should start up with your own projects to understand the working terminology of Apache Spark. Spark’s major building blocks are the RDDs(Resilient Distributed Datasets) and the Dataframes.
• Spark also has the capability to get itself integrated with some of the high-performance programming languages like Python, Scala and Java. PySpark RDDs are the best examples for the combination of Python and Apache Spark.
• You can also understand how to integrate Java with Apache Spark through this amazing Spark Java Tutorial article.
• Once you are having a better grip on the major building block of Spark, you can move ahead into learning the Major Components in Apache Spark which are mentioned below:
  • SparkSQL
  • SparkML-Lib
  • Spark GraphX
  • SparkR
  • Spark Streaming

and a lot more

• Once you get the required training and certification, its time for you to take the most important and bigger leap. The CCA-175 Certification. You can begin solving some sample CCA-175 Hadoop and Spark Certification Examination.
• Once you get a briefer idea and confidence, you could register for CCA-175 Examination and excel with your true Spark and Hadoop Developer Certification. You can refer to a sample CCA-175 Question paper here.
