Subject different dfs block size
Date Tue, 15 Jul 2008 01:43:34 GMT

I'm wondering what would be the memory consumption of
dfs.block.size for a fixed set of data in NameNode? I know
it is determined by # of blocks and # of replications, but
how many memory does one block will use in NameNode?
In addition, what would be the pros/cons of bigger/smaller
block size?
