here are many online trainings available and believe me…Its not quite easy to choose as everyone promises the best. After careful reviews and attending demos, I picked – Edu...reka and I realized that my decision was correct in every aspect. I attended 2 courses - Big Data Hadoop and PySpark. The trainer dived deep into concepts in Hadoop, like pig, hive, Sqoop, NoSQL, and Map Reduce. When comes PySpark too, the trainer explained in detail - Spark streaming, Spark SQL, Spark RDD, Spark Machine Learning libraries (Spark MLlib) and Phython.
