Ambari based uninstall
Team,
I am using Ambari to install a cluster which now needs to be deleted and
re-installed.
Is there a clean way to Uninstall the cluster, clean up all the binaries
from all the nodes and do a fresh install ?
There is no data on the cluster, so nothing to worry.
Thanks in advance

Please take a look at:
https://issues.apache.org/jira/browse/AMBARI-249
Ambari mailing list seems to be better place to ask this question.
Cheers

Hi Steve,
On all your hosts, try running "python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py".
This should delete binaries, directories, alternatives, etc.
After that, run "ambari-server reset" on the ambari-server host. This initializes the Ambari postgres db.

Team,
I am using Ambari to install a cluster which now needs to be deleted and re-installed.
Is there a clean way to Uninstall the cluster, clean up all the binaries from all the nodes and do a fresh install ?
There is no data on the cluster, so nothing to worry.
Thanks in advance
