Subject HDFS addBlock()
Date Mon, 23 Feb 2009 12:50:12 GMT
Hi,

I have a question regarding NameNode.addBlock() function.
I see that it makes sure that the previous block is replicated before you
assign an additional block.
I wonder why it checks penultimate block rather than ultimate block ?
Is it because it would take some time for the immediately previous block to
be replicated?

Thanks,
Sangmin
