Hello,

Sounds like you've had the CM5b1 installer or repo configuration present on this node before and have some lingering repo configuration. You may wish to:

- rm -rf /var/cache/yum/x86_64/6/cloudera-manager/

- yum clean all

Also make sure in /etc/yum.repos.d that you don't have any conflicting repo files that would provide CM5b1 artifacts. What exact cloudera-manager-installer.bin file did you download (full URL)?
