PROFESSIONAL EXPERIENCE:

Confidential

Team lead and Software Engineer

Responsibilities:

• Worked on Hadoop-as-a-service, specifically in the area of provisioning Hadoop in VMs and bare-metal machines on Confidential ’s private and public cloud offerings (SoftLayer acquisition). Provisioning of Hadoop in bare-metal machines was especially challenging. My contributions to Confidential ’s Hadoop as-service were architecture, design, and implementation of the below automated deployment features:
• Chef was used as the provisioning tool. Integrated Ambari, Hbase, Spark, and other Hadoop ecosystem services.
• Programmatically added new nodes to an existing cluster, which in turn included fetching the new node from SoftLayer, installing keys, installing Ambari client along with required Hadoop components and registering the new node with the Ambari server for the Hadoop ecosystem to recognize this new data node.
• Implemented ELK stack on Hadoop cluster. Generated audit logs for Hbase, HDFS, Knox, Ambari, and other Hadoop components. Used Logstash to forward logs to different servers.
• Log Analyzer functionality. Implemented Rete algorithm to classify event types within logs.

Tools: used: Java, Softlayer APIs, Ruby, Chef, Shell Scripts, Derby, RestEasy, Agile/Scrum, Linux, Apache/Tomcat. Conceptual knowledge of Apache Hadoop, Spark, Lambda.
