What is Apache Spark?
Apache Spark is an open source big data processing framework that runs massive amount of data analytics applications across clustered computers. It can process data from a variety of data resources, including the Hadoop Distributed File System (HDFS), NoSQL databases and relational data stores such as Apache Hive.
Spark supports in-memory processing to boost the performance of big data analytics applications and it can also do conventional disk-based processing when data sets are too large to fit into the available system memory.
Why is Apache Spark important?
- Spark is Open Source.
- The amount of data generated around the globe each day is 2.5 exabytes according to Adepta, March 2015 edition, and the big data market reached $27.4 billion in 2014 according to Wikibon, March 2015 edition. Spark is clearly a computing architecture expressly designed for this level of growth.
- IBM made an announcement in June 2015 that it will educate more than 1 million data scientists and engineers on Spark.
- Spark offers more than 80 high-level operations and excels at programming models involving iterations, interactivity, streaming and more.
- Spark is able to make use of the Hadoop File System (HDFS) while at the same time, does not require HDFS.
- Spark supports SQL-based queries and streaming applications.
- Spark’s multi-stage in-memory primitives provides performance up to 100 times faster for certain applications compared to Map Reduce.
- Spark is well-suited to machine learning algorithms.
- There is an increasing demand to support BI workloads using a combination of Hadoop and Spark SQL.
Why the course is most sought after?/ What are the career benefits in-store for you?
- According to the popular IT job portal, Dice.com, a keyword search for the term “Spark Developer” showed 34617 listings as of 16th December, 2015.
- According to indeed.com, the average salary for a Spark Developer in San Francisco is $128, 000 as of December 16, 2015.
- According to O’Reilly, data engineers who have experience with Apache Spark and Storm earn the highest average salaries. Apache Spark and Storm skilled professionals are pulling close to $150,000 in yearly salaries, when compared to the total average salary of data engineers which is $98,000.
- Users find it easy to use, reliably fast, and aligned to growth in real-time analytics.
- Spark is creating opportunities for big data exploration by making it easier for a wide range of people to solve a growing variety of data problems.
- Data Scientists and Data Engineers all want to work with Spark.
- Organizations can use Spark on top of the existing Hadoop clusters as can it run on Hadoop MapReduce as well as YARN and on HDFS.
- With high compatibility of Spark with Hadoop, companies are on the verge of hiring increased number of Spark developers as they do not have to re-invest on computing clusters because it can be integrated well with Hadoop. This also makes learning spark an added advantage for professionals with expertise in Hadoop skills.
- A recent survey on Spark adoption revealed that Spark community has had most of the contributions compared to other open source projects managed by Apache foundation.
- A survey findings show that among Apache Spark adopters 68% of the companies are using Spark to render support for BI workloads.
- Big data predictions for 2016 expect Apache Spark to go its own way, creating a novel, vibrant ecosystem with popular cloud vendors releasing their individual Spark PaaS offerings.
- Industry-wide Spark skills shortage is leading to a number open jobs and contracting opportunities for big data professionals.
- Spark developers are so in-demand that companies are agreeing to bend the recruitment rules, offer attractive benefits and provide flexible work timings just to hire experts skilled in Apache Spark.
