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.

Its simple enough to trace back a FileSystem -> DFSClient -> NameNode call in
code, for the operation of creating a file (and thereafter a block).
What you are looking for, specifically, is in FSNamesystem#allocateBlock(…).
