Selwa,
I'm glad I could help. I suggest you import the source code in an IDE (we
use Eclipse) and navigate around it. The outline view in Eclipse is a
lifesaver :)
BlocksMap does not seem to have that API. I would try FSNamesystem on the
namenode. On the client side, the DFSClient class is what o
Ravi,
thank u very much for your reply.
i am using version 0.21.0 . hope your comment will help me a lot.
BTW, after i got the blocksMap, can i request this blocksMap to return
blocks of a given file.
i mean how to map a filename to its blocks?
Best wishes,
Selwa

Selwa,
You are *creating* a new BlocksMap with the first line. It is NOT an API to
get the blockmap from the namenode. The Namenode stores its blocks in a
Blockmap in the BlockManager (for 0.23) or FSNameSystem (for 0.20)
Which version are you using?
Regards,
Ravi.
