RE: blockID generation
you can find the code directly in FSNameSystem#allocateBlock
It is just a random long number and will ensure that blockid is not created already by NN.

Subject: blockID generation

Hi all,
I am interested in exploring how the blockID is generated in hadoop world
by the namenode. Any pointers to the class/method which takes care of this
generation?
Thanks in advance,
~Kartheek.
