title: Advantages of Sequence file over hdfs textfile
body: <p>What is the advantage of Hadoop Sequence File over HDFS flat file(Text)? In what way Sequence file is efficient? </p>
  
  <p>Small files can be combined and written into a sequence file, but the same can be done for a HDFS text file also. Need to know the difference between the two ways. I have been googling about this for a while, would be helpful if i get clarity on this?</p>
