       You are right. Even I ran into the same hurdle recently and just
raised our concern with Cloudera team. You can join the discussion
https://groups.google.com/a/cloudera.org/group/cdh-user/browse_thread/thread/56bc678ff473a15f#

       It is just with the recent release, the new VM released is out of 64
bit Cent OS. Where as the previous versions were based out of 32 bit Ubuntu
OS.(I do have the 32 bit one but size is too large to be send across by any
means). You can check with the Cloudera archives. (not sure where you can
find the link to older versions, need to reach out  Cloudera team for
help).
