A recent survey states that the big data professionals having Spark skills have enjoyed hike in their
salary. If we consider the statistics from any part of the world, the conclusion will be- to learn Spark. The
big data project known as Spark introduced by the Apache Software Foundation has influenced the
analytics world with its increasing speed. It won’t’ be wrong to say that now Spark can be seen as a
competitor of Hadoop software.
Understanding the Apache Spark
Apache Spark is an excellent framework that is helpful in executing general data analytics over the
distributed system as well as computing clusters like Hadoop. Apache Spark enables in-memory
computations at higher speed while the low latency data process on MapReduce.
It doesn’t replace Hadoop, rather operates atop the already existing Hadoop cluster for accessing the
HDFS or Hadoop Distributed File System. Apache Spark can also process structured data in Hive and
streaming data from Twitter, Flume and HDFS. Madrid Software Trainings provides complete practical
hadoop training in delhi.
What Makes Spark Stand Out?
It has been observed that Real time stream processing is getting popular among all the big data
functions. It means analyze the data as it is captured and feed it back to the user. Spark can also create
difference in the field with its amazing speed. It is excellent when it comes to operating machine
learning algorithms. These are the most critical reasons why Spark is popular and the demand of Spark
developers are on rise.
Hadoop Vs Spark
If you are aware of the latest trends in the world of big data, you must be aware that Hadoop has been
there for quite some time which has made it a most widely used software system for various big data
operations. The advent of Spark has created confusion among many enterprises. Having similar features,
they both boast of their unique features and can produce great results if worked together. So, if you are
making up your mind for Hadoop training, move ahead as it is the right time. Spark big data training will
add benefit to your career if you are already involved in Hadoop oriented functions. Madrid Software
Trainings is rated as the best hadoop institute in delhi by professionals.
Whenever there is a discussion on the topic of Hadoop, the comparison with Spark happens. Reason
behind Hadoop’s popularity is that the Hadoop Distributed File System or HDFS. At a time, when
organizations were apprehensive about their data yet they could not afford the quantity of storage
space needed, HDFS brought in an easy solution at reasonable price. The other tools offered by Hadoop
like MapReduce were enjoying a decent job. Spark came in and influenced everyone with its speed. It
copies the data into faster RAM memory right from the distributed storage system. Spark’s in memory
operations happen 100 times faster than similar Hadoop tools. But it does not offer any distributed file
storage. So Spark and Hadoop both should work amazingly with each other- Spark for analyzing it in a
flash and HDFS for data storage.
Future of Spark
The main feature of Spark open source software system that appeals users is, it is cheap and affordable.
With the type of functionality and speed offered by Spark, it is just a matter of time when the world
starts looking for Spark developers. The analytics industry is all set to experience a global shortage of
many professionals within coming couple of years. So it is always better to pre plan your career and get
enrolled in Spark big data training.
Apache Spark vs. Hadoop MapReduce
As we know that Apache Spark is helpful in in-memory data processing, while Hadoop MapReduce does
I/O operations on the disc after each and every map and reduces actions. It further boosts Spark’s
processing speed which can outperform Hadoop MapReduce.
It can be said that Apache Spark could replace Hadoop MapReduce but when it comes to Spark, it
requires a lot more memory. MapReduce ends the processes once the job is accomplished, hence it can
operated with some in-disk memory.
Apache Spark works well with iterative computations when cached data is used again and again.
Hadoop MapReduce operates better with data which doesn’t fit in the memory and while other services
need to be executed. Spark is designed for instances where data adjusts in the memory particularly on
individual clusters. Being written in Java, Hadoop MapReduce is difficult to program whereas Apache
Spark is known for its flexibility and ease of usage APIs in languages like Scala, Python and Java.
Professionals can write user-defined functions in Spark as well and they can even add interactive mode
to run commands.
Observing its speed, flexibility and ease of using, Spark can be accepted more widely. Chances are there
that it can replace MapReduce. But we cannot ignore the fact that there are still some areas where
MapReduce will be in demand, especially when non-iterative computation takes place with availability
of limited memory.
