I want to replace a new CDH version 0.20.2+320 with an older one 0.20.2+228.
"yum downgrade" reports that version can only be upgraded. I also didn't find a
way to yum install the older version.
I guess I can download tar ball of the old version and extract it to where the
new version is installed and overwrite it. But seems not a good solution
because it might have negative impact on upgrading in the future.
So, what is the best way to do this?
Thanks,
Michael
