Upgrading Hadoop from 0.18 to 0.20

I have Cloudera's vmware image which has Hadoop 0.18 version which I want to upgrade it to Hadoop 0.20. I tried to follow instruction given on Cloudera's site about upgrading CDH1 to CHD2 but it fails to find required packages. Please let me know if there are any instructions to be followed.

Can you be more specific with the steps you followed and the error messages you encountered? The training VM isn't anything "special," it's just Ubuntu. You should be able to configure it to read from the new apt repository and update all the packages.

Thanks,

I was trying to install CDH2 using this APT repository : http://archive.cloudera.com/debian

I used # apt-get install hadoop-0.20, to install this distribution and it gave me error "E: Couldn't find package hadoop-0.20"

So I followed same steps using It seems that I am using wrong repository

so, I tried to follow steps given on :
http://archive.cloudera.com/docs/_ins...

But still it couldn't find required packages.

Finally I downloaded hadoop-0.20 from apache and installed on vm.

Are you sure that you have apt configured to use our 'testing' repository?

yeah, I followed this too. When I added these repositories, and tried to install, It gave 404 error for "packages.gz".

I suppose whole path was :

Put the following in a file called hadoop.conf in /etc/apt/sources.list.d

deb http://archive.cloudera.com/debian hardy-testing contrib
deb-src http://archive.cloudera.com/debian hardy-testing contrib

I am using Hardy here so change it to whatever release you are using...

I’m happy
