2. Will any input files be stored in fsImage.
3. When a namenode goes down will all the data in the name node go down or just the meta data only and what will happen to fsimage & editslog.
5. Is the fsimage file which is also maintained as a backup on multiple data nodes and secondary namenode or it just sits on a namenode.
6. Does fsimage sit on hdfs or namenode server.
6. What exactly does the editsLog do?
