• I design scalable web services for data tracking
• I test software prototypes and supervise its’ transfer to operations

My Skill-set includes:

• Hadoop Distributed File System (HDFS)
• Hadoop Distribution Platforms: Cloudera, HortonWorks, MapR
• Java MapReduce
• HBase and HiveQL
• Pig Latin Scripts
• Multi-threading and concurrency concepts
• Data Loading Tools: Flume and Scoop
• Workflow and Schedulers: Oozie

I am Happy because I am quite confident about my future. 
I am happy because I am earning well and Job trends indicate fortunate years for me ahead.

See what Indeed.com points out:

I test the Hadoop application under consideration. My responsibility includes finding bugs and carrying out the process of troubleshooting. I make sure that the MapReduce jobs, HiveQL scripts, and Pig Latin scripts are tested properly so that they work under all scenarios without any trouble.

I am also responsible for:

• Constructing test cases to find bugs
• Creating reports about defects
• Finding and reporting defects to the managers and the development team

I have an in-depth knowledge of:

• Java
• MapReduce
• JUnit
• MRUnit
• Hive and Pig

I am a Happy Hadooper because this profile is interesting and promises professional growth.

I am a system administrator, specializing in Hadoop, therefore known as Hadoop Administrator. My roles and responsibilities include administration of Hadoop infrastructure. I team up with Hadoop developers and testers in order to deploy hardware and software environments.

Let me compile the roles and responsibilities of a Hadoop Administrator:

• Managing cluster connectivity and security
• Removing nodes with the help of tools such as Cloudera Manager Enterprise and Dell Open Manage
• Managing HDFS maintenance and support
• Working closely with data scientists and business application teams to provide data
• Setting up Linux Users and ensuring Hive, Pig, HDFS, and MapReduce access to users.
• Reviewing Hadoop log files and monitoring file system
• Escalating the final product to the vendors

I am skilled in:

• Linux
• Oozie, HCatalog, Hive
• HBase, Pig, Mahout
• Deployment tools: Puppet, Chef, Linux Scripting
• Deploying Hadoop Cluster and adding and removing nodes
• I have knowledge of troubleshooting, bottlenecks, storage, and networks

I am Happy with my profile. 
I am happy because I have a steady career with a handsome salary.

I analyze, manage, and streamline complicated data sets. I am responsible for devising tools to enhance the information flow to the organizations for business benefits. I analyse data coming from varied sources to help business houses derive business intelligence so that they can take intelligent decisions and make good business policies.

Have a look at my roles and responsibilities:

• Extract relevant data for analysis
• Work on data modeling standards
• Create predictive models for deriving business intelligence
• Work on data mining architectures and data analysis methodologies
• Analyzing business requirements and developing big data analytics projects accordingly

My skill set is as follows:

• Mathematics, Statistics, and Programming
• Data extraction and manipulation, and data analytics
• Pig, Hive, SQL
• SAS and R

I am Happy because I have the “sexiest job of the 21st century!”
