In my previous role as a Big Data Administrator, I gained extensive experience with Hadoop and Spark. I was involved in the complete process of Hadoop cluster setup, which included installation, configuration, and monitoring. I also worked with Kafka for stream processing of data and had hands-on experience troubleshooting various issues with Hadoop components like HDFS and YARN. Additionally, I have experience with cloud platforms, particularly AWS, where I handled Cloudera cluster installation and configuration. This role required me to manage and optimize cloud-based data warehousing solutions, ensuring efficient data processing and storage management.
