Using HDFS what to do

Using HDFS what to do

Simply I can say by using basic formula,
  • Hadoop = Store + Process  
    • Store = HDFS  
    • Process = MapReduce  
So, final result is  
  • Hadoop = HDFS + MapReduce
  • (Please don't apply the maths formula like
    • Hadoop - MapReduce = HDFS
In Hadoop,  
  • HDFS is used to store the data.
  • MapReduce is used to process the data.
  • HDFS is specially designed file system to store large data sets.  
  • HDFS is a highly scalable, distributed, load-balanced, portable, and fault-tolerant storage component of Hadoop.  
  • HDFS has been designed to run on commodity hardware.
Thanks for your time.
