Over recent years, Big Data technology has experienced explosive growth within the IT market. Revenue Lines Of Code now surpasses $50 billion.
conducted a global client survey, discovering that 64% planned to invest heavily in Big Data Technology.
Relational databases cannot process and manage the enormous and diverse amount of information Google Cloud Platform organizations generate worldwide, making Apache Hadoop an excellent solution to handle Big Data.
It provides flexible, economical, fast, and robust handling.
Hadoop Project for Hive Analytics Using SQL and Scala
Here are five reasons Java developers should consider learning Hadoop
The Natural Progression Of Java Professionals
Hadoop was written entirely in Java, making learning the platform simpler for Java experts. One of Hadoops core modules, MapReduce, is a hallmark; Apache Pig is its development platform.
Pig Latin is an advanced platform that uses Java MapReduce Idioms to simplify MapReduce Practical Experience programming, thus making MapReduce programming as accessible and high-level as SQL databases used by traditional relational databases.
Java-skilled professionals will find their Java knowledge helpful when writing User Defined Functions that extend Pig Latin.
Furthermore, Java expertise may come in handy when debugging Hadoop apps.
Learning Hadoop Separates Java Professionals
Java developers may be easy to come by, but they dont stand out either. Professionals trained in Hadoop have an edge against Big Data challenges if combined with analytics; businesses worldwide use Hadoop because it makes business sense, so Java developers with Hadoop skills are always sought.
Apache Frameworks provide high-level abstractions such as Pig and Hive for map reduction Java Virtual Machine programming.
Pig Latin or HiveQL programming languages may be used. Eventually, these programs will be converted to Java MapReduce programs for Hadoop use. Streaming can also help develop map-reduce functions; however, some advanced Hadoop features require Java API-only access.
Java professionals with knowledge of Hadoop have an advantage over their peers when it comes to understanding any modules function in Hadoop code and its operation, known as Hadoop Module Understanding (HUM).
This gives Java professionals an edge over others.
Let us examine one Redditors experience to understand why Java professionals may switch to Hadoop. Reddit user describes his journey into landing a job as a Hadoop Developer at one of the companies providing popular Hadoop Distributions; before taking this position, he had four years of experience programming Java before enrolling in a month-long Hadoop course aimed at understanding the ecosystem.
He didnt need to know about every tool; demand is sufficient that knowing both tools suffices!
Work On Industry-Oriented Hadoop Projects To Become A Hadoop Developer
has identified which Hadoop job openings would best fit Java developers. According to , Java developers should avoid becoming Hadoop architects as that requires significant experience; recruiters seek someone capable of designing Hadoop workflow or solutions that junior Hadoop Artificial Intelligence programmers can implement themselves.
