Dears,

   I just joined HDFS dev mailing list. I am currently researching HDFS
interface for security mechanism. May I know how to get authority of
checking out HDFS codes? Thanks!

Anyone can check out the code, I would recommend the git mirrors:

http://git.apache.org/

Thanks for reply. But I find the codes are not zipped, so not to be
downloaded at one shot. Can I check out the code via CVS? If so, what's
the server configuration and directory info for downloading the codes via
CVS? Sorry for the simple question. Hope to get your reply. Thanks.

You need to use Git (http://git-scm.com). It is a source control tool like CVS, but better suited to large distributed projects.

Thanks for help. I could check out codes. Are there any documentation for
setting up debug environment for HDFS? Should Single Node HDFS be set up
for debug purpose? Should Hadoop Common codes be checked out for
running/debugging HDFS? Or can HDFS alone be enough for run/debug? Sorry
for the simple questions. Hope to get reply or any advice to new comer for
HDFS.

Hi Min, look at the unit tests which make use of MiniDFSCluster -- you can
run those in debug mode and step through the code, and they include a bunch
of use cases.  That's generally much easier than running all of the
different services and debugging each separately.

Hi, Jay, Thanks for reply. I can see "TestBlockRecovery" and
"TestDataDirs" for datanode; also "TestGetImageServlet","TestINodeFile"
and "TestNNLeaseRecovery" for namenode. I will start from these first
then. Thanks.
