Re: fsImage & editsLog questions
1. Will fsImage maintain the data/metadata of name node.
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?
Please pour some light.
Thanks
Sai
