Subject Is there any Namenode block scheduler which considers the block load
Date Tue, 11 Oct 2011 11:08:10 GMT
Scenario: If I run huge number of jobs(all these jobs will use the same
resources(input files)) on mini cluster(say 10-15 nodes), then every time
namenode returning the first block of nearest data node. So in this case all
the clients are trying to do read/write operations on same block.

So is there any other namenode scheduling which considers the block level
overhead?
