> Currently when a block is deleted, DataNode just deletes the physical file and updates
its map. We need to update more things. For e.g. numBlocks in FSDir is not decremented.. effect
of this would be that we will create more subdirectories than necessary. It might not show
up badly yet since numBlocks gets correct value when the dataNode restarts. I have to see
what else needs to be updated.
