Hello Ashoka, "Learning Spark," from O'Reilly, is certainly a good start, and all basic video tutorials from Spark Summit Training, "Spark Essentials", are excellent supplementary materials.
And the best (and most effective) way to teach yourself is really firing up the spark-shell or pyspark and doing it yourself—immersing yourself by trying all basic transformations and actions on RDDs, with contrived small data sets. I've discovered that learning Scala & Python through their interactive shell, where feedback is immediate and response is quick, as the best learning experience. Same is true for Scala or Python Notebooks interacting with a Spark, running in local or cluster mode.
