Systems Engineer

Responsibilities:

• Created an Apache Hadoop (Big Data) fully distributed POC cluster install using HDFS, MapReduce and its various sub-projects, Pig, Hive, HBase and Oozie.
• Sub-Expert with HDFS and MapReduce in a Linux OS. Effort involved installing Hadoop and configuring Hadoop environment using .bashrc & hadoop-env.sh.
• Configured the Hadoop framework (provide JDK and SSH password-less keys from NameNode to all slave nodes).
• Configured the NameNode (create the masters and slaves files).
• Modified core, hdfs and mapred-site.xml files used to configure the nodes.
• Then format NameNode and verified the configuration.
• Troubleshot the cluster using log files and the node web user interface to correct errors, and finally shut down each node (decommissioned the DataNodes as well for practice).
• Used Fs shell, fsck and dfsadmin tools to interact with HDFS. Throughout effort performed unit testing on MapReduce portion under Eclipse IDE to eliminate bugs before entering job onto cluster. Once bugs were eliminated put job onto cluster to verify it worked. Made liberal use of the web user interface to verify all nodes' status in the cluster.
• A key producer in designing a 'user friendly' Database using ACCESS to replace the ESS log books in ESS Lab.
• Worked on the ‘next generation’ CEC SDP-S terminal. Responsible for evaluating CEC CCAs that comprise the CEC (Cooperative Engagement Capability) terminal.
