How to learn big data analytics with R?



I am working as a Data Scientist from 2 years and we work on only structured data. I have decent experience with extracting data from SQL Server and Oracle, writing queries. I am trying for a new job now but the big problem am facing during the process is most of the recruiters and interviewers are asking about experience in NoSQL,HDFS,Spark.My experience is with R and I want to know where can I learn the integration of hdfs with R and what is Spark and how we fetch unstructured data into R.I am in huge confusion and literally have no idea where to start and what should I learn.
Please throw some light at me
