Navigating the Data Lake: Deploying Hadoop/HDFS and Spark on Kubernetes

Introduction:

In the modern era of data-driven decision-making, organizations are constantly seeking innovative solutions to harness the power of big data. One such solution is the deployment of Hadoop/HDFS and Spark on Kubernetes—a strategic endeavor that requires careful planning and execution. In this blog post, I will explore the process of deploying these technologies on Kubernetes, unlocking new possibilities for data management and analysis. This is the same solution that we used when we started to build our no code/low code data pipeline and visualization platform DataSetu. For Datasetu we needed to create a Data lake for processing huge dataset with high performance. This how we went about it,

Chapter 1: Setting the Foundation with Kubernetes

Before embarking on our journey to the data lake, it's essential to establish a solid foundation. Kubernetes serves as the cornerstone of our infrastructure, providing the orchestration and scalability needed to manage our distributed systems efficiently. With Kubernetes in place, we are ready to proceed with confidence, knowing that our environment is robust and reliable.

Chapter 2: Deploying Hadoop/HDFS: Building the Data Fortress Our first destination in the data lake is the realm of Hadoop/HDFS—a proven solution for distributed storage and processing. By deploying Hadoop components on Kubernetes, we construct a formidable fortress to safeguard our data assets. With meticulous attention to detail, we configure HDFS settings to ensure fault tolerance and data integrity, laying the groundwork for seamless data management.

Chapter 3: Igniting Innovation with Spark As we venture deeper into the data lake, we encounter the dynamic landscape of Apache Spark—a powerful engine for large-scale data processing and analytics. Deploying Spark on Kubernetes enables us to leverage its advanced capabilities while maintaining flexibility and scalability. With Spark as our catalyst, we unlock new possibilities for real-time insights and predictive analytics, driving innovation across our organization.

Chapter 4: Optimizing Performance and Reliability In the ever-evolving world of big data, optimization is key to maintaining a competitive edge. We invest time and resources into fine-tuning our Kubernetes environment, optimizing resource utilization and maximizing performance. Through careful monitoring and proactive maintenance, we ensure that our Hadoop/HDFS and Spark clusters operate at peak efficiency, delivering reliable results and driving business value.

Chapter 5: Documenting the Journey As our deployment journey nears its conclusion, we take a moment to reflect on the lessons learned and achievements gained. Documentation becomes our compass, guiding future endeavors and informing best practices. By capturing insights and sharing experiences, we contribute to the collective knowledge of the data community, paving the way for continued innovation and success.

Conclusion: Deploying Hadoop/HDFS and Spark on Kubernetes is a strategic initiative that empowers organizations to harness the full potential of big data. By leveraging these technologies in a Kubernetes environment, businesses can achieve greater agility, scalability, and efficiency in their data operations. We have seen that with DataSetu platform. As we navigate the data lake, let us embrace the challenges and opportunities that lie ahead, knowing that with the right tools and expertise, the possibilities are limitless.

Exporting/Saving Putty/SecureCRT/SecureFX sessions on Windows!!

This is my first stint with blogging and I thought why not just start with sharing some useful information/tricks  that can save you some time. To begin with , here are couple of tips that could save you some time. Actually, I had once this problem where I have to take backup and move my work data to a new laptop and as we normally do , I also put my data on some external drive and copied it to the new box. During all this exercise I realized that by this I can only back up the data, what about the work I am doing..my configurations and installations...? What the heck...I need to spend lot of time to redo all that...crap. I was using Putty, SecureCRT and SecureFX to log on to client side boxes and to work upon. And all three had at least 30 saved sessions having IP/user/pwd information, reconfiguring those sessions would be a daunting tasks. I did some research "well by that I meant googling also..:)" and here is how a little information can help you.. If you are usin

What is big data ? and what role Hadoop has to play?

In recent times we have been hearing , reading (in many blogs) quite often about cloud computing ,big data and HPC ie. high performance computing. Undoubtedly, these are the buzz words for this decade. If you have been in the industry for quite some time then you can recall last decade was web 2.0 decade. So what is big data? Is it a new framework or new data modelling technique or part of NO SQL movement? I have seen many times people relate big data to one of these or they are confused about it. Same is with HADOOP, it is thought as a NO SQL database framework. Big data is nothing but just huge amount of data which requires mining. Per wiki , Big Data is a term applied to data sets whose size is beyond the ability of commonly used software tools to capture, manage, and process the data within a tolerable elapsed time. Big data sizes are a constantly moving target currently ranging from a few dozen terabytes to many petabytes of data in a single data set.So big data is a hovering p

class.forName(String className) used in JDBC unfolded

During many interviews I have taken , I have observed even seasoned programmers find it difficult to explain the use of class.forname() method while making a JDBC connection object. In this post, I am just trying to explain this, Here is a simple JDBC code, import java.sql.*; public class JdbcConCode { public static void main(String args[]) { Connection con = null; String url = "jdbc:mysql://localhost:3306/nilesh"; String driver = "com.mysql.jdbc.Driver"; String user = "root"; String pass = "nilesh"; try { Class.forName(driver); con = DriverManager.getConnection(url, user, pass); System.out.println("Connection is created...."); //TODO //rest of the code goes here } catch (Exception e) { System.out.println(e); } } } Let's go through the code above, the url indicates the location of the database schema, here the database is nilesh . Then there is Driver which is the fully qualified JDBC driver class name.
