Hi Balto,
What's happened is that your new machines ended up getting CDH4.1.3 and the
old ones are still on CDH4.1.2.
You can either upgrade the old ones (using yum update) or downgrade the new
ones (by specifying the CDH4.1.2 repo and using yum downgrade). See
https://ccp.cloudera.com/display/DOC/CDH+Version+and+Packaging+Informationand
https://ccp.cloudera.com/display/DOC/CDH+Packaging+Information+for+Previous+Releasesfor
more information.
Cheers,

Hi folks,
I am using Cloudera Manager Free and trying to add a new host to CDH4.1.2
cluster. After installing the new host, host inspector said "there are
mismatched versions cross the system.", and I cannot enable datanode since
task tracker cannot be started. My previous MR version is 552 but version
of the new host is 556. Even I ran "Re-run Host Upgrade Wizard", the
problem cannot be resolved (seems nothing changed, still version mismatch).
What should I do to resolve this problem?
