Skills Required by a Hadoop

• Basic knowledge of Hadoop and its Eco-System

• Able to work with Linux and execute some of the basic commands

• Hadoop technologies like MapReduce, Pig, Hive, HBase

• Ability to handle Multi-Threading and Concurrency in the Eco-System

• The familiarity of ETL tools and Data Loading tools like Flume and Sqoop

• Experienced with Scripting Languages like Pig Latin

• Good Knowledge of Query Languages like HiveQL

Roles and Responsibilities of a Hadoop Developer

Now, we will move into the key topic of this article, the “Roles and Responsibilities of Hadoop Developer“. Every company has its own operations running on its data and the developers associated will also have to fulfil the respective roles accordingly.

• Strong grip of Hadoop and its Eco-System

Understanding the basic suit that provides the solution to big data is mandatory. The basic components of Hadoop, which are the HDFS and MapReduce should be learnt. Later comes the data accessing tools like Hive, Pig, Sqoop. And finally, mastering the data management and monitoring tools like Flume, ZooKeeper, Oozie.

• Comfortability with Linux and execute dome of the basic commands

If you are stepping into the world of Hadoop, then chances are there that you might start learning Hadoop using any of the popular distributions like Cloudera CDH and the Hortonworks HDP.

These platforms help you speedup learning by providing a tailor-made platform where most of the services in the Hadoop ecosystem are already running. You can start writing MapReduce jobs right away.

These distributions mainly use one of the Linux flavours. For example, Cloudera CDH uses CentOS. Having some comfortable understanding of Linux and its flavours will help to smoothen your learning curve.

I strongly recommend gaining some competency in Linux while or before learning Hadoop.

• Hands-on Experience with Hadoop Core components

Hadoop is the technology that the future relies on. Hence, making real-time and data-driven decisions happens to be a crucial move. This can only be achieved when you get real-time hands-on experience with the Hadoop systems

• Developing Hadoop and implementing it with optimum Performance

The main motto of Hadoop is to provide High-Performance oriented data systems. This can be done by coding the Data processing algorithms like MapReduce in an efficient way and balancing the load among all the available nodes in the cluster.

• Ability to Load data from different data sources

Data is being generated every single second. The sources are limitless. Every single piece of electronic equipment generates data. starting from the sensor to the satellite. Hadoop system should be capable enough to load in the data from multiple sources for the domain it is designed for.

• Design, build, install, configure and support Hadoop system

These 5 stages in a Hadoop System are crucial, A Hadoop Developer should be capable to install, build and configure a Hadoop System. This happens to be the basic requirement for every Hadoop developer.

• Ability to translate complex technical requirements in detailed a design

Hadoop is the most wide-spread technology used at a global level and different companies using it have their own requirements. A Hadoop Developer should be capable enough to decode the requirements and elucidate the technicalities of the project to the clients

• Analyse Vast data storages and uncover insights

Hadoop is undoubtedly the technology that enhanced data processing capabilities. It changed the face of customer-based companies. Based on the artificially intelligent systems, it is now possible to identify customer requirements and make decisions with little human interaction.

It becomes a crucial role for every Hadoop developer to own the skill to analyze and generate the respective reports based on the collected data.

• Maintain security and data privacy

Every company has its own gravity for its data. It might be sensitive information like customer data, transactions made, company’s confidential information. It becomes the priority of every Hadoop Developer to maintain strong Data Security and Privacy to protect the company from potential cyber threats.

• Design scalable and high-performance web services for data tracking

Hadoop stands superior when it comes to performance and reliability. Hadoop Developers are should be able to design the Hadoop System to be highly scalable and withstand any unexpectable calamities that are prone to data loss.

For example, the Hadoop System should always maintain a standby node which can take up the position of the current node when the current node encounters and unexpected failure.

• High-speed data querying

The major role of any Hadoop Developer is to make sure that there is enough memory available both on the Query-end and the Server-end. The Buffers, Indexes and the Joins play a key role while dealing with a huge amount of data.

In case if enough memory is not available to the system, then there are possibilities that the system might tend to slow down.

• Loading, deploying and managing data in HBase

HBase is designed and developed to host huge tables of data for interactive and batch-mode analytics by running NoSQL o top of Hadoop. Its parallel data accessing ability in distributed systems make it the most capable, fastest and scalable data store for Hadoop Framework.

Having sound knowledge in working with HBase would be an added weight on a Hadoop Developer’s Resume.

• Cluster Coordination services through Zookeeper

Apache ZooKeeper provides the best in class service to connect, coordinate and maintain a Hadoop Cluster. It gets in synchronization with all the nodes in a cluster using the most robust techniques and providing the simplest User Interface.

Being comfortable with ZooKeeper Services would be beneficial for a Hadoop Developer to design any Hadoop cluster with strong connectivity.

Now, let us discuss the different business sectors that are looking for Hadoop Developers.
