Hello Mithra,

Big data is a field that modulates ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with. Big Data is transforming the IT data landscape with its emerging data management approaches  and analytic technologies that support the business. Big Data professionals are demanded and employed by IT companies like Facebook, IBM, Google, and also by businesses of non-IT sectors.

Some of the Big Data Skills that are in high demand are as follows:

Apache Hadoop - Professionals with knowledge of the core components of the Hadoop like HDFS, MapReduce, Flume, Oozie, Hive, Pig, HBase, and YARN are and will be high in demand.

Apache Spark - Spark is being preferred as a faster and simpler alternative to MapReduce, either within a Hadoop framework or outside it.

Data Mining and Machine Learning - Big data professionals who can leverage machine learning technology to build and manage predictive analytic applications such as classification, recommendation, and personalization systems are in high demand.

NoSQL - Most big enterprises are increasingly using distributed, scale-out NoSQL databases to meet their data storage needs, resulting in a demand for professionals equipped with skills of NoSQL.

Data Visualization - The knowledge about data visualization tools like Tableau, Qlikview is preferred as they come handy during complicated affairs.

General Purpose Programming - Knowledge of general-purpose languages like C, Java, Scala, Python, etc are another set of skills that companies look for in individuals.

R, SAS, MATLAB - Experience and expertise in statistical tools like R, SAS, SPSS, Matlab, or Stata, can help one lock down the Big Data job that they are seeking.

Hope this helps you. We wish you the best for your future endeavours!
