Answer 
U know first of all we can directly store the data in memory rather than in disks for which my RAM management will be volatile where I can easily loose data but that will cause a problem with my metadata so immediately I have to create an interval offtime within which I have to create a disk where I can store the backup of my metadata which is basically called as FS IMAGE but again it will become big right ,so suppose today FSIMAGE is subdivided in two versions FS1 and FS2 there the backup of your data is done within every 24 hrs but as it's regularly not possible to backup my data daily we have to create a small file where we can easily store the backup of all our activities and that file is called as an editlog then we will surely not loose our metadata and some of the huge stored files will also get pushed up in Hadoop. Well I don't have a much knowledge about all these things whatever I have said just from my basic knowledge,I just wanted to try, so please don't mind or comment anything if I have done a mistake by answering this question.
