How can I get a job as a Hadoop/Spark engineer?

When considering a career as a Hadoop/Spark developer, the amount of education and training necessary is a critical factor. While a college degree is commonly required for most Hadoop roles, it can be difficult to obtain such a degree with just a high school certificate. Therefore, it is important to ensure that the chosen major is suitable for the desired position. Our research has revealed that the most common degrees for remote Hadoop employment are Bachelor’s and Master’s degrees. Additionally, diplomas and associate degrees are also accepted qualifications for many Hadoop/Spark engineering roles.

Having a background in a related field such as Java Development can be extremely beneficial for those interested in pursuing a career as a Hadoop/Spark engineer. In fact, many roles for Hadoop/Spark engineer positions require previous experience as a Java/J2ee Developer or Senior Java Developer. This experience can be invaluable in preparing for a successful career in this field.

Qualifications for a Hadoop/Spark Engineer

As a remote Hadoop/Spark engineer, certain aptitudes and abilities are essential to success in the role. While businesses and organisations may have varied preferences when it comes to these skills, the following is a comprehensive list of abilities that are typically required for such a position. It is important to note that there is no need to possess expertise in each of these areas; rather, a working knowledge and proficiency in the majority of them should be enough for most people.

1. Fundamentals of Hadoop

   When you have determined to begin looking for a position as a remote Hadoop/Spark engineer, it is essential to gain an understanding of Hadoop concepts. Being familiar with the features, applications, advantages and disadvantages of Hadoop will be immensely beneficial in the process of mastering more complex technologies. To gain a better understanding of the subject, reading tutorials, journal articles, research papers, attending seminars, and exploring other online and offline resources can be incredibly helpful.

3. Computer programming languages

   It is commonly recommended that individuals looking to study Hadoop Development familiarise themselves with Java, as the language was used when creating Hadoop. However, to gain a comprehensive understanding of the subject, it is also advantageous to become proficient in other programming languages such as Python, JavaScript and R.

4. SQL

   To ensure success in your role, it is essential that you have a comprehensive understanding of Structured Query Language (SQL). Supplementing this knowledge with familiarity in other query languages, such as HiveQL, will further enhance your abilities. To further develop your skillset, it is recommended that you review and refresh your understanding of database principles, distributed systems, and any other related topics.

5. Fundamentals of Linux

   It is highly recommended that you acquire a thorough understanding of Linux fundamentals, as the vast majority of Hadoop projects are based on this platform. Additionally, during your studies, be sure to cover related topics like concurrency, multithreading, and similar topics.

6. Hadoop Components

   Now that you have gained an understanding of the fundamental concepts of Hadoop and acquired the necessary technical skills, it is time to examine the Hadoop ecosystem in its entirety. The Hadoop ecosystem is comprised of four main components: the Hadoop Distributed File System (HDFS), MapReduce, a Resource Negotiator, and YARN. HDFS is a distributed file system which facilitates data mapping and reduction. A Resource Negotiator has been appointed to ensure that Hadoop is being utilised to its fullest potential. YARN is the resource manager for the ecosystem, which enables and manages applications and resources on the cluster.

7. Languages of Interest

   Once you have gained an understanding of the core components of Hadoop, it is essential to become familiar with the appropriate query and scripting languages available, such as HiveQL and PigLatin, to effectively operate within the Hadoop environment. HiveQL (Hive Query Language) is a query language that is used to process structured data that has been stored. The syntax of HiveQL is closely related to Structured Query Language. PigLatin, on the other hand, is a programming language used by Apache Pig to analyse data stored on the Hadoop platform. In order to effectively work with Hadoop, it is important to be knowledgeable in both HiveQL and PigLatin.

8. ETL

   It is time to delve deeper into the world of Hadoop development and become acquainted with some of the key Hadoop technologies. Extract-Transform-Load (ETL) technologies such as Flume and Sqoop are essential for loading data. Flume is a distributed program used to aggregate, collect and transport large volumes of data to HDFS or other central storage systems. On the other hand, Sqoop is a Hadoop tool used to connect Hadoop to relational databases. Furthermore, familiarity with statistical applications such as MATLAB, SAS and other similar programs is also important.

9. Spark SQL

   Spark SQL is a module of Spark which is used for structured data processing. It provides a programming framework known as DataFrames and can also handle distributed SQL queries. Moreover, it is well-integrated with the other components of the Spark ecosystem, enabling the combination of SQL query processing with machine learning tasks. To be able to compete for remote Spark developer jobs, you must develop a mastery of this skill.

10. Streaming using Spark

    Spark Streaming is an extension of the Spark API that allows data engineers and scientists to monitor and analyse real-time data from sources like Kafka, Flume, and Amazon Kinesis. After examining this data, they can then write it to file systems, databases, and even create live dashboards to display the results.

11. Spark DataFrames and Datasets

    Spark Datasets are an evolved version of Data Frames and offer two distinct types of Application Programming Interface (API) characteristics: strongly typed and untyped. As opposed to Data Frames, Spark Datasets are composed entirely of strongly typed Java Virtual Machine (JVM) objects and leverage the capabilities of Spark’s Catalyst Optimizer for enhanced performance.

12. GraphX library

    GraphX is an integrated platform which facilitates the combination of Extract-Transform-Load (ETL), exploratory analysis and iterative graph computing. Its Pregel Application Programming Interface (API) enables users to keep track of the same data in graphs and collections, rapidly exchange and combine graphs by using Resilient Distributed Datasets (RDDs), and craft custom iterative graph algorithms.

How can I get work as a remote Hadoop/Spark engineer?
