Description
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.
