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.
