Hi, during the Cloudera Developer Training at Berlin I came up with an idea, regarding a lost name-node. As in this case all data blocks are lost. The solution could be, to have a table which relates filenames and block_ids on that node, which can be scaned after a name-node is lost. Or on every block could be a kind of a backlink to the filename and the total nr of blocks and/or a total hashsum attached. This would it make easy to recover with minimal overhead.
Now I would like to ask the developer community, if there is any good reason not to do this? Before I start to figure out where to start an implementation of such a feature. Thanks, Mirko
