> There appears to be some places in Namenode that allow reducing memory
> consumption without intrusive code or feature changes. This bug is an initial
> attempt making those changes. Please include your thoughts as well.
> One change I am planning to make :
> Currently one copy of each block exists for each of the replicas and one copy
> for blockMap. I think they are all supposed to be same.
