Thanks Bryan. I was able to bring up CDH4. Trick was, as you said, to remove "previous" subdir.   Cheers Upen ... View more

Hi Bryan, Error says: InconsistentFSSTateException: /srv/namenode is in in inconsistent state. previous fs state should not exist during upgrade. Finalize or rollback first.   Now, my question is if I would be able to reconcile my fsimage later when I take back up.   Thanks Upen ... View more

I am at a point where I am upgrading namenode using "sudo hadoop-hdfs-namenode upgrade". But it is compalining because it is conflicting with old Fsimage (CDH3). If I delete the old fsimage, I lose all my data. How can I safely upgrade. Please help. This is one step where I can't afford to be adeventurous 🙂 ... View more

Thanks Bryan for the prompt reply. That should work for me I guess. I like the idea of creating a brand new cluster and then use distcp. But unfortunately, we don't have a new cluster which we can leverage. So I will have to do with other option. Did you have any major challenges during upgrade ? Did your map reduce code compile well under cdh4 ?   Thanks Upen ... View more

Hi, I am trying to find instrictiions to upgrade to CDH4 from CDH3U6 bypassing cloudera manager completely. For that I need to create local yum rep on RedHat. Instructions at http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/latest/Cloudera-Manager-Installation-Guide/cmig_create_local_repo.html requires to install CDH4 and use parcels. I would like not to install it. Rather, I am looking for a Clouder CDH4 repo file which I would like to inside my firewall and then install all the RPMs from this repo. But I am unable to find the repo file. Do I need to download TAR file instead and see if that comes with REPO file inside of it. Has someone gone through this exercise before. I was hoping this should be straigthforward but loooks like it isn't. Please help.   Cheers Upen ... View more
